In a sense it already is. The ultra-wealthy own and run the businesses which supply everyone else with all those things, and their wealth is largely just the nominal paper value of a whole bunch of successful attempts to supply society with things. What doesn't and cannot happen is redirecting their wealth in the sense that a lot of the American left imagine, where we can just take their billions and turn them into billions of dollars of healthcare or housing or anything else that would benefit the less wealthy. The reason this isn't possible is that their wealth doesn't represent actual resources they're claiming. When we say that someone like Jeff Bezos is worth $150 billion dollars, that doesn't mean they're personally using $150 billion dollars worth of land, materials, equipment, people's time, etc that can be redirected into houses or healthcare, whereas someone who buys a $200 TV is making use of something like that amount of actual resources that cannot be used for anything else. Houses and healthcare need land, materials, and lots of workers' time, which then cannot be used for other things, and it fundamentally has to be the people who'd have those other things who ultimately pay for this.
