Talk about a gross oversimplification. Venice grew out of mosquito infested lagoon due to necessity. The Venetian people were driven into the lagoon multiple times over centuries as a means of protection from Germanic invasions in the 7th century. They capitalized on shipping and trade just like any other population would do and used those riches to make their citizens lives better. What would you have expected them to do? Turn away from the money spice trading and Mediterranean shipping traffic brought them because it would make them too rich? Because again, they were a people used to fleeing into a mosquito infested lagoon when their farming population was invaded by multiple armies.

For that reason, comparing an entire cultural population like Venice to a singular person is a false equivalency. Bezos hasn’t used his shipping fortune to enrich anyone but himself, but at least Venetian royalty built buildings and public spaces for their population.
