Quoted from taylor34:So if you spend 46,000, after 5 years you'd have 54,000 in earnings + 30k in machines or $84k
If you just spent that in the stock market taking the last 5 years as a benchmark, you'd have 46,000 * 90% gain (with dividends reinvested) = $87,400
Plus the stock earnings are taxed less, no work, etc.
Past performance is not an indicator of future returns. It's good to invest of course but the market could turn at any time.
