I'm not disputing the claim that few people are able to save and invest into having a stake in the means of production. However, if your goal is to increase stakeholdership, how would a policy that explicitly disincentivizes that behavior fix anything?
Well for a start it pressurises asset holders to sell their assets. But the point isn't to increase stakeholdership so much as to stop privileging stakeholders with very low effective tax bills relative to mere workers, which means that there's a lot less cause for concern about those workers not owning their means of production
Even assuming this is true, then what? Do you think the average joe is going to suddenly buy alphabet or meta stocks because bill ackman or ken griffin sold their shares to buy bigger yachts?
