NY produces a lot of art / culture, but as with most things more than 90% of it is crap. If you don't feel like shifting through it then living in NY is pointless.
Or maybe you just don't care for modern city culture. I find a long walk in the woods more enriching than a world class art museum, though the latter has better bragging rights.
Seriously, humans lived in societies for thousands of years without the billion forms of stimulation that we have today. I refuse to believe their lives were in any way deprived because of this. The demand for an urban lifestyle is completely artificial and only serves to create a steady supply of desperate workers filled with envy of movie star lives. Humans in primitive societies today still manage to live happy lives. What would aid us all is to realize our desires are not our own but implanted by marketing to benefit the power elite.
