First off, it's not a crazy idea, and you're right, many have had it before. John Lennon said, "Imagine."
The problem lies in your plan.
Turn that money into love and give people hope...
How? That's not exactly a technical or scientific process. If you can figure that out, we can get somewhere.
Money is the only system we have, and it's far more fair than other systems we've tried, like slavery and indentured servitude. It's not without it's flaws, and sometimes undeserving people come out on top (and bottom). Do you think most of those people know the kinds of joys others do though? I may not know what it's like to go to sleep on a mattress of women and gold every night, but I know what it's like when my daughter screams laughing because I gave her a butterscotch or a stick. Having that much of it presents problems too, such as never being able to trust anybody, ever, in some cases. How lonely and hellish would that be? There are worse things in the world than dying broke.
I feel what your attitude is, but you have to stop looking at money, birthrights, ignorance and selfishness with such malice. Why should anyone be mad at the Kardashians for being rich, except if they are letting jealousy run their ideals? Why shouldn't you say, "We should all be rich." Life isn't fair, and it's not just money that does it. It is nature.
However, if you want to put so much judgment on people and decide what's right or wrong, then why don't you place the blame at the top where it rolls down from? Snobs are rich. Animals eat people. Sister got sick and died. Seems like nature (God) is a bigger commonality than anything else. There is a chance that none of us understand what is really fair, right, or wrong. To me, there is no black or white, there is only greys.
As a side note: One of my ex-girlfriends is heading out to Africa next month to help install water wells and windmills. I'm just proud of her and she seems to be on the right track as far as helping her fellow man out, even if she is doing it under the guise of organized religion.
Just hold a door open for a nasty dirty bum or a rich, well dressed old lady. We're all in this bitch together, and we shouldn't let the jealousy take such a hold of us. Jealousy is the reason people don't share so much in the first place.
