I consider Warren Buffet as very honest though he openly admitted to have used tax loopholes to the fullest, which is not illegal. His remaining other lifestyle appears very moral and honest. The Google top execs also provided true value to the world and they most of the time adhered to laws and regulations but probably are further away from Buffet on the tax loophole scale. An example of the worst are the Sackler family members behind Purdue pharma and the Koch family...Elon plays various games, leaves California for taxes just to beg for subsidies in Texas, to have others pay for his low quality garbage cars. A life of decisions that show low regard for doing the right thing and moral values all in the pursuit of money and fame.
And those 1/4 have probably already passed. In todays atmosphere of putting short term profits above anything else, even long term profits; you are left with very little wiggle room. peace.
