You realize the money these rich folks retain isn't in their personal money bins? They keep it in banks who loan it out so people can buy things and businesses can expand. The only times money does not go back into the economy is when you put it under your bed or when it goes to the government.
Name me someone who makes 250K and is among the top 5% in US earners who ain't rich. That percentile has an average net worth of $3.1 Million.
