I love Rabid conservo-speak... answer your questions rather than ask vague questions... Fact is Walmart is moving away from full time workers, past part-time workers and hiring temp or contract workers as they get ZERO benefits and depending on the method of filing, zero unemployment compensation when they are let go- a process called churning. since you brought up the youth unemployment rate, just how many workers at Walmart are 'youth'?
Now about the hamburger BS... Walmart is like the rich guy handing his workers 3 hamburgers for the week knowing full well the taxpayer- something Walmart has a very sketchy past with- will keep the worker fed, clothed and medically taken care of. In a way Walmart is the wave of our future, corporations de-facto making the government responsible for the worker's well being.
Walmart has already gone to all the places, and left a wake of crashed small businesses for miles around each store here in Oklahoma, DC is the last frontier, I guess like farming marginal land, all the other places are under plow. I can see them having an 'Alexander the Great' moment. How far into the wilderness can you go? How much land area do you have to occupy? When is big, big enough?
The question to ask is will Walmart bring in NEW jobs or displace workers and small business owners for a net loss? Walmart isn't Mercedes, USA. Nor is it Beretta USA- Walmart doesn't build anything, it doesn't provide anything new to the consumer- just more of the same at cheaper prices. People were getting their TVs, T-Shirts, Jeans, and groceries someplace before Walmart showed up. Those places employ people, have owners, pay property taxes. Given what I've seen of Walmart's coming to rural America, I'd say it isn't a win-win for any area.
