At a dinner party, a friend said that the biggest problem in Taiwan now is the M-shaped society. This society is like a tree. The more saplings you have, the more energy you will get from the sun, and the more leaves you have, the more fallen leaves you will have, and after the fallen leaves have decayed, naturally there will be ants, fungi and earthworms to convert the decayed leaves into fertilizers, and so the stronger you will be. According to my friend, the richer the person is, the more resources he can get, and the more money he has, the faster he can accumulate wealth. He thinks that in terms of education, the better the environment at home, the better the children will be.
