$3,000/mo. — that’s over $36,000 a year! Where do NYers work that pay them a salary to afford that kind of rent???
Plenty of industries here pay more than enough for that rent to skilled proven professionals. There are also many business owners due to the density. Each block full of office buildings houses hundreds, sometimes thousands of businesses. Many companies here do business with the entire world. One building I visited today housed a defense contractor, a high end frilly fabric factory, a software designer, one of the best bridge designers in the world, an air cargo company and at least 10 other firms I didn't recognize.
Not to mention all the owners and investors of so much super valuable real estate.
Lots of action here in NYC if you have the drive and talent.
