Lets use this as an opportunity to count how many countries actually managed to deliver on making brand new emergency ventilators during the emergency?

I counted only three: Turkey — Baykar Biyovent, Pakistan — Kamra PakVent 1, India — Marutu Suzuki emergency ventilator. That's very few.

Even if NYC government didn't dish those money to him, it would still be unrealistic to expect anybody being able to deliver on that in any capacity, other than existing manufacturers.

How they didn't know that?

Similarly, the story with PCR tests. Those were available at least a month prior to emergency in NYC, yet USG spent sweet time dishing out random grants and contracts, despite the solution already being on the table.
