As a Miami resident, it’s clear that Miami is extremely influenced by NY and NY’ers living there to begin with. So I’m not sure if this is really news. NY’ers essentially built up what is Miami now and there is a strong sphere of influence from NY in Miami.
Miami is basically a satellite economy of NY. The big thing that Miami doesn’t have is high paying jobs. And tech in Miami is virtually nonexistent.
But wealthy folks residing in Miami don’t really need to worry about landing a decent job in the first place.
