<prompt> Human: I am being shown that minimum wage salary is 15k yearly. Putting 15 of your earnings into savings comes out to about 2.2k yearly, amounting to 90k after 40 years. If you live to 85 after retiring then youd have to spend 4.5k a year to make it.I am only using todays wages instead of prior years and it still seems like it would not be enough to live off of. I assume the number would be less than 90k total saving if inflation was factored. I am assuming people will soon start living longer than 85 so i dont get how youd be able to retire off of minimum wage.  <response>: 6 in the SP500 in 1970 equals 73 in 2016. This is why there is so much info in the sidebar and wiki about how to use index funds.
