American CEOs are on the board of 8 companies but spend 5 minutes a year combined at the offices of those companies. They spend their weekends at private islands off the coast of the US Virgin Islands with other billionaires. They fire employees who ask for health care benefits or a day off. They actively endorse political candidates who went to the same private island with them and who will lengthen working hours, reduce benefits, and make it easier to fire employees. They want global surveillance to track anyone who's ever even considered saying anything bad about them. When it's possible to inject ads directly into our brains, those CEOs will force their employees to do it.
As an American who's been in Japan for a very long time and worked at Japanese companies, Japanese companies don't pay big bucks, but there are fewer deranged ultra rich people within them.
