That model is outdated. Inflation in prices and housing are going up well over 10% per year, so the worker bee is always behind the curve, and loses financially year on year.
If the rich guy makes 90,000, and the worker makes 10,000, when there is a 10% increase, the rich guy makes 99,000, the po folk gets 11,000 theoretically. The poor can never catch up.
Of course the Uber wealthy are small time employers, the middle class guys running a diner, or employing landscapers gives more back to the country than Bezos or Gates. Then of course, the rich can deduct everything, the working man cannot even deduct the gas, food, clothing, training or the workers comp. What the rich guys make is pure profit after deductions.
Why should they? An equal distribution of income and wealth assumes that productivity is equally distributed. It is not. Why should someone who doesn't graduate from high school makes an equal income to the person with a Ph.D. or M.D.? A lot of people think Bezos and the Walton family don't deserve to have that much wealth and income. However, those same critics did not create 200,000 jobs for people who live on that income, nor did they create almost 1 million jobs that Walmart created. This kind of thinking is "modern" but, alas, totally naive and wrong. Some people glorify the poor and I think that is simply wrong. Some people are poor because of circumstances beyond their control. However, the vast majority of the poor are so because of bad decision making. I have regret for the first group and absolutely none for the second. There are just too many examples of people who bootstrapped their way out of poverty through hard work.
