Why do you want access to other people's riches?
If we can ensure that no single individual has to live below the poverty line then I'm less worried about individuals who attain huge stores of wealth.
Who needs more than one pair of shoes?
Who determines what other people need?
Maybe we should forget we are adults and have a governing body tell us why we need so we don’t have to think about it?
Otherwise many are under the impression that looting and robbing is a way to go.
"...educate others how to earn good money and live a good, productive lifestyle".
You may add to that many other educational resources and lots of them are free. People who are willing to learn will learn.
People who are unwilling to learn and prefer to rob and loot - will continue doing so.
Also, if the billionaires give a tiny amount of their money to fund schools, people will get educated, earn more money and be able to spend more.
And governments of course has a ways to convince them that doing that is not wise.
High taxes is the easiest way to deplete economy from productive individuals and their resources.
Taxes literally are used as a tool to incentivize investing in the economy.
I'm sure taxes has all the good intentions but how well does it work so far if trillions of dollars are escaping in direct opposite directions?
If the tool doesn't work at all - in fact instead of building it just breaks stuff - wouldn't it be a good idea to try a different tool?
It might be, or at least a step in the right direction, if those billionaires were teaching free wealth acquisition classes as a full time job after they attain three commas.
Many of the wealthy are born into wealth and have family and institutions that help them maintain it. The poor won't have a start like that, so we might have to setup pools of money donated from these billionaires for the poor to start out with. It could even have a catchy slogan too. Something like, "No exploitation without education."
