It is certain that societies are immature. People seek to protect their own private interests which reduces the net social benefits from the economy. It is a problem worldwide.
As far as elected officials, many people do not understand how to maximize net social benefits from the economy, so they choose a candidate based on religious, moral or cultural beliefs. Then these politicians promote the wrong economics that decrease net social benefits. This too is a worldwide problem.
It takes a mature person to understand how the economic resources of a country can be managed to increase net social benefits.
For me, the primary goal of economics is to increase net social benefits to society in general.
When the rich in Nigeria, for example, hoard the wealth for petroleum and do not pay taxes, the poverty seen in Nigeria is very understandable. The wealth of the nation is not being shared among the people of the nation. It is being hoarded by the fortunate few who control the money.
There is an old Navajo saying. "A rich man is someone who does not share his wealth with his family." The rich need to share their wealth with the people of their nation.
But, people have justified not paying taxes by saying that the taxes are not used properly. On many levels, that is a cop out.
