Do you think the wealthy will always become more wealthy? As an example, if Bill Gates invests $100,000,000 at a paltry 1% interest rate he earns $1,000,000 in interest. If you or I invest $100,000 at 20%, we earn $20,000 in interest. Bill Gates increases the "wealth spread" by $980,000 dollars! How do we "compete"? (or should we just worry about ourselves as we now have an additional $20,000?)
