1. OCCUPY WALL STREET and the problem of capitalism
- "Occupy Wall Street is leaderless resistance movement with people of many colors, genders and political persuasions. The one thing we all have in common is that We Are The 99% that will no longer tolerate the greed and corruption of the 1%."

- The value of money differs to people. Meaning of 1 million won can be nothing to an employer, but can be really important thing to an employee. With this aspect, it is obvious that we should distribute money to the poor more.

2. low birth rate and the future society
- The tremendously expensive price to raise a child is forcing the poor people not to give a birth to a baby. This leads to the collapse of the current system, which is hardly held by low-paid workers.

3. Marx's das kapital and the lesson we should get from

- The owner of house earned the money simply by borrowing his house. The bank will earn money by interests also. This is quite similar to the analysis of Marx, who viewed the monopoly of the means of production is the reason of the gap between the rich and the poor. Although the communism failed, there certainly is a lesson to learn from it, especially nowadays when the problem of capitalism is highlighted.
