I think last time this happened a bunch of anti media consolidation laws were passed to prevent rich people from owning everything (unfortunately they were repealed in the 90s in the US) Also taxes, wars. Basically rich people will fund wars to ensure people don’t take their money but in doing so they destroy their money because wars kill workers, destroy products and produce nothing of value.

Its easier just to tax rich people and break up the large conglomorates they’re using to rig everything. Tech companies would need to be included here.
