Wealth Distribution

I think there is a problem with how wealth is distributed amongst the population, I am not fond of the accumulation of wealth to the level of billionaires and I believe that this excess wealth is a fault and should be redistributed. I envision a world where billionaires are taxed appropriately and those taxes are used to solve or at least positively contribute to major social and environmental issues, not to pad the pockets of politicians. Closing tax loopholes would be a big step towards this, as well as taxing assets such as stocks, not just liquid cash.
