The higher education system in these countries (US, Korea etc) has become like a theatre in which some people decided to stand to get a better view, promoting the others behind them to stand. Once enough people stand, everyone has to stand, which means no one is getting a better view, while everyone has become more uncomfortable.

The free market doesn't exist. Every market has some rules and boundaries that restrict freedom of choice. A market looks free only because we so unconditionally accept its underlying restrictions that we fail to see them.

Making rich people richer doesn't make the rest of us richer.

95% of Economics is common sense deliberately made complicated.

Equality of opportunity is not enough. Unless we create an environment where everyone is guaranteed some minimum capabilities through some guarantee of minimum income, education, and healthcare, we cannot say that we have fair competition. When some people have to run a 100 metre race with sandbags on their legs, the fact that no one is allowed to have a head start does not make the race fair. Equality of opportunity is absolutely necessary but not sufficient in building a genuinely fair and efficient society.

Assume the worst about people and you get the worst.

We are not smart enough to leave things to the market.
