The median US income is $31,000; it's $34,000 in NYC. I assume most people here make more than that because they have disposable income to hire providers. And I assume most of us do not have the expense of children. Our income is MANY times that, but the juice still has to be worth the squeeze.
Ultimately, for us hiring is a matter of convenience. We don't wish to waste our time on apps, and we don't hang out in bars or clubs much anymore. So the cost of hiring has to be worth saving that time. And for us that is generally going to fall in the $250-$400/hour range.
