Forced wealth redistribution will not work. In fact, if anything, it is counterproductive. You have to ask yourself why certain cultures and societies have flourished and advanced like they have while others languished and remained mired in poverty.
Until you change those things about a society that produce those negative results, that society will never advance. Those changes could take many generations to occur, and they can easily be disrupted or stopped by returning to just some of the past negative practices.
Welfare, for example, is not a hand up, but a handout for most who receive it. It generally disincentives work and self-betterment. At the same time, instituting confiscatory levels of taxation to pay for it only incentivizes cheating, black markets, and even simply giving up and becoming a welfare recipient rather than work hard and have the results taken from you.
