The stuff most billionaires buy doesn’t really appeal to me.
But I think it would be really cool to beautify/improve my city with schools, museums, ornate fountains, bridges, etc.
I would like to be heavily involved and the patron of an elite charter type school in my community (I have a lot of thoughts on that)
I would like to have a beautiful parcel of private forest land like 10,000 acres + in one spot close to my home.
Boats, planes, art, watches, jewels, wine collections no thanks.
