Being happy is relative and dependent on the individual, his culture, his religion, his mindset e.t.c
There is really no point to having over a few million dollars. Once your basic needs are met, extra money won't do much for you. I consider people like jeff bezos and bill gates to be real psychos. Bezos treats his workers like slaves. Bill Gate's "foundation" is nothing more than a depopulation, vaccine giving, evil money fund.
It's mostly just a power thing. Billionaires wan't the power to control how the government makes laws.
I have always argued this with people back home to be some sort of conspiracy theory against Bill. The so called evil money fund is responsible for the total elimination of polio in my country, an act the corrupt ridden government has failed to do despite the huge resources and funds at its disposal.
They cry depopulation and I laugh. For the sake of argument, let's agree there's a depopulation agenda by Bill's foundation, in my opinion it worths it in my home country. You find people who can barely survive on $1 a day marrying 2 to 3 wives and giving birth to 10, 15, 20 children. Who will feed them? Who will pay their school fees? Who will pay their medical bills when they fall sick? Who checks on these kids as they grow up and become nuisance to the society as they as easily absorbed into criminal and terrorist organization!
