Tbf wealth distribution doesn't tend to come up in liberal circles, it isn't really a liberal policy in the traditional sense, and has mostly entered the liberal sphere of consciousness as of late because liberals and progressives are forced to share a single political party/coalition in most electoral eco-systems.
Not to mention how there's a lot of different philosophies on how to go about it even among strident proponents of redistribution.
For example, I believe in a tax bracket system which adjusts the actual bracket amounts year to year based on household percentile income, and where the actual amounts taxed relate to the share of the wealth controlled by those brackets, with lower brackets being taxed at share, and the highest bracket being taxed three times their share of the wealth.
Not only does it provide a dynamic system of taxation that naturally adjusts to year to year economic conditions, but it also places an upper limit on how much the ultra wealthy can control before it starts biting them, and in the process, begins incentivizing them to sabotage each other to keep their overall rates as low as possible. The rich would be eating each other for us.
Now to some that is an incredibly radical idea, while to others it's the furthest thing from radical since it doesn't involve brutally murdering factory owners in front of their families.
