I would only invest in the S&P 500 with a short term time horizon. In other words I would try to time the market.
The rich might make 3% on a safe investment while the average homeowner will feel good about having a 3% mortgage but if you take the difference, 6%, and over 10 years, the rich person will be 80% richer on the same investment as the homeowner (is homeowner one word?) that folks is why the rich get richer and the poor get poorer in a nutshell. I’m sure the rich will probably make more than 3% when invested professionally and credit card debt is way higher than any mortgage rate which is a real drag on the poor person’s balance sheet.
I bought in at 23900 and plan on selling at 25000 (DOW).
Probably should have used 3.6% in above example for mortgage and investments for a doubling of disparity.
