RE: How Much Money Is Enough?
The more stuff you have, the more it costs to maintain it. If you buy a "dream house" and a "dream car" all of a sudden you are trapped into paying property taxes.
At todays interest rates and risk profiles there is no amount of money that is easily attainable by the middle class that can earn passive income sufficient to maintain their standard of living indefinitely.
At 1% interest it requires 7.5 million dollars to earn $75,000 per year. That would require the typical middle class individual to save 100% of their income for more than their working life span. Once you factor in minimal cost of living and inflation and taxes, game over. It isn't even remotely possible without taking extreme risks in the market.
Someone who earns $7.5 million dollars after taking extreme risks in the market will still fall behind unless they continue to take extreme risks. Negative real interest rates are a bitch.
