I like the inclusion of trade school: https://jakeseliger.com/2018/03/12/the-case-against-educatio..., as a lot of modern college education is bogus: https://jakeseliger.com/2014/04/27/paying-for-the-party-eliz.... I've been on the supplier side of it, and the extent of the corruption in the system is understated.
