paper money is far from perfect, but it is the best we can find

today. No matter what currency system we pick, politician and wall street people will win, since losers already disappear from public eyes. It was this way in the old days when we only use gold and silver in China, rich people are always politician and business man. 官和商。

Wall street is just an efficient way to pool people's money together for mordern world's mass production, without wall street, there will be no freeway systems, communication systems, utility (electricity, water) systems, or put it another way, cost will be much higher, like what is going on now in North Korea.
