To what extend new products should be regulated?
Because of competition there is immense pressure to get the product to market fast. This is true with pharmaceutical as well as financial products. Without a government agency as a gate keeper, society will be the lab mouse of innovative products. Some products are safe to use the public as lab mouse – remember the days when Windows crash daily? But others will have severe consequences, such as death or global financial crisis. To what extend new products should be regulated? What’s the right balance between safety and efficiency?

What caused the failure of Mortgage Back Security?
MBS is expected to work the same way. Because the pool of mortgage from across the country, and from borrowers who work for different industries, it is assumed that default won't happen en mass. In statistical jargon, default would be independent event.
This independent event assumption works under normal condition. But under certain circumstances, the assumption can be completely wrong. In the life insurance case, when a deadly flu virus sweeps through a country, or a major war breaks out, or a large scale natural disaster strikes, people can suddenly all die at the same time. The events are no longer independent, because one underlying cause links all of them.
The current financial crisis starts from mortgage suddenly default en mass. The underlying factor is low interest rate for an extended period of time. Low interest rate causes housing price to go up nationally, because the same monthly payment can buy more expensive houses under a low rate environment. When housing price shots up too high, it can no longer be supported by income. Naturally it would have to come down a bit. When it comes down people with weaker credit and lower income start to be late on their payment. Market re-priced their risk and their interest rates went up. Now they can no longer affort the monthly payment, their bank foreclosed their houses. Foreclosure depresses housing price, causing even tighter credit. More delinquency ensue followed by more foreclosure. A downward spiral accelerates.
En mass default of mortgages means risk sharing no longer work. Banks understand that the MBS and CDO they hold as assets worth less. But how much less? It is difficult to value. The complexity of these financial instruments blocks transparency. The lack of transparency results in a confidence crisis on counter party default. Credit suddenly freezs, LIBOR and commercial paper rate shot up. Consumer credit deteriorates, and bank solvency becomes an issue.

Wall Street Meritocracy is based on wrong accounting
Business will always have cycles. In good times the profit is overstated. Inflated housing price is sure to fall at some point. But Wall Street compensation never factors in this fact. If they are rewarded for the good times, it is only fair that they suffer at the bad times. When investors see huge losses in their pension portfolio, Wall Street executive don't get negative number of compensation.
My conclusion: Wall Street executives are not compensated according to performance. They are having a call option on business cycles: hugely rewarded at good times and immune from bad times. Is this meritocracy? Is this pay for performance? Or is it just ripping benefits of economic growth while avoiding the unavoidable slumps? At a minimum we should not call such lopsided compensation meritocracy. It is based on incorrect accounting.

Taiwan Independence
Although the Chinese economy is growing briskly, China remains an autocratic regime. Government power is arbitrary and sustained by gun and nationalism. Tibetan protests are suppressed with ruthless military action. Human right advocates receive jail time rather than Congressional medal-of-honor. Internet is censored so people of grievance lost their voice. It is scary under Chinese rule.
Because of this nature of Chinese government, difference in regional interest will be resolved by gun rather than in court. Taiwan has no chance of winning any difference.
Taiwan’s president Ma is improving the relationship with China. But he would be foolish to surrender Taiwan’s sovereignty. It is Taiwanese sovereignty that guaranteed the freedom of its people, including the rights to sue their own government and replace a bad government by election. This is the only reason that an $11 billion worth of weapon purchase from the US can be justified. It is the price we paid to have political freedom.

The question of suffering
God's Problem: How the Bible Fails to Answer Our Most Important Question--Why We Suffer (Hardcover)by Bart D. Ehrman (Author)
1. God is omnipotent - all powerful.
2. God is a loving god.
3. Why are there mudslid and tsunami that causes so much suffering?
Is suffering God's intention? How can that be loving?
Is God not capable of stopping it? How can that be all powerful?
Why would God murder all ten of Job's children just to test his faith? Is that love?
Author was an evangelical Christain and at one point a priest. After 20 years of searching for an answer he becomes an agnostic.

Death Tax? Prevention of dynasty.
This is a threat to the freedom of most of the population, baring the privileged few. Yes, the Congress and the Senate is in favor of repealing the estate tax - an unjust death tax in their words. No surprise considering the fact that they are the privileged few. But the rest of us should remember that they are not having our best interest in mind. Nor do they have our children's best interest in mind.

God
Dad had it wrong. He approaches the religious question with a scientific/detective mind. He trys to find evidence of God's existence and found nothing there. But the question is not a scientific or empirical one. It is a humanity one.
I ask another question: why since ancient time people around the world - from oceanic islands to continental India to the Middle East - have their own religion? Isn't this prevalent existence of religious practice a proof that people needed God?
When there is no God, people create their own God. Muslim, Budism, Christianity, Judaism, Greek Gods, or idol worship, religious practice is an important part of life since ancient time from a cultural anthropology perspective.
I guess God is created because life is painful. We face hunger, cold, disease, war, power struggle, and toil for a living in our lives. God is the ideology, the faith, the mindset needed to deal with all these.
Humanbeing created God, because we are in need of a God. It is in our human nature to have faith, and with that faith we are connected with something larger than our lives.
