Per day costs, sure. But if you add recurring payments, don't think they are outspending it. Also, you are ignoring the entire point to begin with. A City should look after it's long term residents first and foremost. Unless you want it to eventually become a ghost city.
>>A City should look after it's long term residents first and foremost.
I don't see why it should. A city should look after those within its boundaries, whether they're there for a day or a year. It shouldn't set up walls and promote long term residence over visits.
So a citizen of a country and a visitor of the country should get equal rights and opportunities as well?
Opportunities? Yeah, although that's not the case now, I'm ready for a world where people have the same opportunities regardless of the text on their passport.
Another short-term resident would be there in his place on the days he's not in NYC. Year round there will almost always be someone staying in his unit.
And short term renters tend to spend more per day than long-term residents, so they probably contribute significantly more to the city's tax base.
