Well, there's definitely other ways. I would prefer a system where company ownership public and private has a mandatory public stake in both ownership and voting on company policy and major business decisions.

I would prefer it illegal for the wealthy to possess an excessive amount of assets. If your assets became more valuable than the limit, the asset share would automatically rebalance toward other employees and owners in the organization who are below the asset ownership limit.

You don't even really need UBI if healthcare, housing, food, and education are considered basic human rights that are included and free of cost at point of usage.
