"More than half of Americans, 52 percent, are currently not investing in the stock market—either by buying individual stocks or mutual funds, or through a retirement account such as a 401(k) or IRA, according to a new Bankrate.com survey. Among the non-investors surveyed, 53 percent said they don't have the money to invest and 21 percent said they don't trust stock brokers or financial advisors."
To me, a $45 start anyone working can figure out. Part of the problem if you ask me is the normalization of the notion of "you can't", etc. I've been reading Mass Flourishing and The Complacency Class this past week; the "you can't" notion, the loss of risk aversion seems to be the key driver. However I think it's also where we put of value regarding information. Instead of watching a sports game or the Bachelor, read a few books about investing and trading which you can get at a library; worldcat.org can help one find such libraries that hold those collections. However many would scuff if they were told to make that trade off.
this is the problem, some people are working and can't really spare a single dollar, much less 45 of them.
Its like saying you can absolutely not sleep an hour a day less to do something productive youd really love to do.
To me the whole 'it can't be done with some people' is just an excuse to be risk averse.
