Somalia and Hait
have surprisingly rich citizens. Just very few. The vast majority are grindingly poor.
The most important in any economy are definitely NOT the rich. They show deplorable tendencies to hoard their wealth, a failure to re-invest, and a generally selfish attitude when it comes to taxes.
They are, in a word, "entitled". The middle classes are without doubt the most important members of a civilized society, shouldering the majority of the tax burden, and generating (through their actual work) most of the wealth. Plutocrats simply make money out of money by economic "trickle up".
