Some trivial facts about students
This morning in the microeconomics book I found an explicit description about the trade-offs between study and work. Your payment during student life is lower than that you will obtain after graduation. It also says the following; you can spend your 4 years of college life going around with friends in parties. But remember, study is some sort of investment in future income. If you spend time for playing, you will less get paid.
Those are so obvious facts but the interest thing is that, most of students in Japan do not understand that fact. I agree with them to the point that they enjoy life, but if they had wider view to future, they would not do the same. Ironically, economics students are known to be lazy.
