The classic Maya had a higher level of inequality than other Mesoamerican societies, due to being more autocratic.

Ironically, this may be linked to the ancient monuments that make the Maya so fascinating to us.

I think it is important for a society to use some of its wealth to make glorious lasting things that can fascinate the public, present and future.

Lasting things do not have to be buildings or art. Condors and whales are glorious, too, so saving them counts.

Making glorious things does not require the extreme inequality that the US suffers today. What it requires is to tax the rich enough to have money for society's needs — including glory.
