A country sells its citizenship. Fair transaction, or citizenship devalued?

Honest question: how is this different from immigration already being tied to investment?

Money in. Real estate boom. Healthcare strain. Politics skewed toward whoever pays. Bad math.

If the country needs revenue that badly, sell it. But don't pretend the person next door who was born here doesn't feel the difference.

Works fine in practice for small island nations. Gets murky when scaled up.

When you sell citizenship, you're selling access to rights, votes, welfare. That fundamentally weakens what citizenship means for everyone already there.
