I am breezing past it because it is wrong. You can observe this by the fact that most buildings do not have them. They are, at this point, an NYC luxury oddity.
I live in an apartment without one and I would not pay $150/month for a dedicated doorman so that delivery people have an easier time with the intercom.
And honestly, you are undercounting the cost, you can't get away with 3 doormen for 24/7 coverage and the salary is not the all in cost. It's probably closer the $300/month for 145 apartments.
If you're already paying $10k/month for an apartment, sure, you don't care about the cost and are happy with the fringe benefits. This doesn't change the fact that the vast majority of people have an intercom because the main function is solved.
