What I want to mention but didn't make in my post, is that interest applied to our existing money system creates 3 monetary groups.
The first group works for their money, 80% of the planet, work their entire life unless their is a welfare social net
Countries compete with each other with trade, financial, manufacturing, and education to move their lower portion of their 80% population to the higher end of the 80% group, this sometimes displaces workers economic power from one country to another.
The second financial group, 80%-90% of the planet, live from the interest in their savings. They cannot spend more than the interest earned from their savings.
All citizens in any country will do any sort of activity to be in this monetary category.
The third financial group, 90%-100%, (and the 1% and .1%), earn increasingly amounts of money from their savings than they can invest or incentive businesses creation that did not deter the money return
Bill Gates loses money by stopping to pick up a dollar on a sidewalk (making new businesses may be not in their interest)

Nations also want to have the greatest access to billionaires to provide access and understanding of interest earning money to grow this population in their nation. This group of people are capable of producing large high risk, most large projects fail, infrastructure and innovation projects.
