In theory, we know how to do wealth redistribution, AI or no AI: tax value creation and wealth transfer, such as inheritance. Then use the money to support the poor, or even everyone.
The problem really is political systems. In most developed countries, wealth inequality has been steadily increasing, even though if you ask people if they want larger or smaller inequality, most prefer smaller. So the political systems aren't achieving what the majority wants.
It also seems to me that most elections are won on current political topics (the latest war, the latest scandal, the current state of the economy), not on long-term values such as decreasing wealth inequality.
