You might want to check the Inglehart–Welzel cultural map of the world. It's amazingly interesting and their data are online. It shows the "tribes" and what influences them. It's on: https://www.worldvaluessurvey.org/wvs.jsp

I think one way of taxing the rich is by simply having high taxes on luxury goods. So if you buy a yacht that costs $100M you will give $50M back to the citizen. This is what the value-added tax is doing but unfortunately, most governments cap it.

I am no economist but I think that would incentivize companies to lower their prices to remain below a certain tax threshold, increase efficiency in their production, but at the same time keeping quality high to attract rich consumers.
