Most rich people (as in very rich) are into the new trend of employing glorified accountants and private bankers called wealth managers. It is their job to advise these rich people on the best tax havens, the best yachts to invest in to avoid taxes, the best schooling to invest in etc, in short the best ways to keep their money in their families. It's pretty much a scam, or depending on how much you like your capitalism it's fine because for example the Grand Cayman Islands are very competitive in free market for tax 'services' (read 'evasion').

So if Bill Gates wants to avoid paying taxes (over and above the vast amount he pasy in taxes anyway) by investing billions of dollars in a charitable research foundation to help stop disease fair play to him.

That's without even going into the crooked financial interactions of the multi-million dollar Gulf War and the usual Dyncorp, Blackwaters, Halliwell Burton crap that this admin is up to it's unwashed neck in.

And as for the fifties and sixties, govts and corporations were still literally using slave labour in some countries, and forced migration and land confiscation and all the rest of it in the name of a few bucks, so it may be time to change those rose-tinted specs.
