In 20 years, there won't be a single independent business left in NYC. Every place you could shop in NYC will be nothing more than another chain store that you can find in any major city.
I live in a small town and that happened here also, we are to small for Walmart, but Kroger, Dollar General, CVS pharmacy, Rural King, ect. and of course Fast Food restaurants have replaced all the one owner shops on main street. In the larger towns Walmart came in and drove most of the small shops out of business also.
It's a shame I really miss the little shops with out much inventory, but the guy behind the counter could get you anything you wanted in a week. They each had distributers who could get anything under the sun, and no matter what you needed or wanted you could order in those little shops.
I wear a 4E shoe and in the 70's and 80's it was easy to get me in a new pair of shoes, not now in 2014.
I also remember when the people who worked at shoe stores knew shoes. The people at Hardware Stores knew hardware, and home repair and could walk you through anything. Every shop had someone there who knew his job and did it well for his customers.
If you went in to a grocery store there was a meat cutter in the back who would take orders for what ever kind of cut of meat you wanted, and when you had your cart full from the rest of the shopping there was a wrapped package in the cooler with your name on it. (few places do that anymore)
I can also remember when the short order cook at the grill made your food right in front of the counter, and it was clean. The staff took pride in the little diner and you could tell. Now the kitchen is just a place were they warm up food in a microwave. (at least in my area)
I am just in my 40's and already sick of the era I live in. By the time I'm in my 80's I will be positively disgusted with the world. I think we peaked as a civilization before I was born!
