Walmart raises much to help the country, they make a lot of money, and they use it to build things, help out schools, hell you can get scholorships from walmart, when the hurricane katrinia hit, walmart donated a lot of money, and funded a lot of food for people down their. I know this cause i worked there.
also ill tell you how they make a lot of money, they cut the cost of shipping on there items, cause they re-use the same boxes until they are torn up. they ship all there crap in the same boxes, and they re-use them over and over and over agian. This saves them ALOT of money, so they can reduce their prices.
just don't work their, the pay is shit and its not worth dealing with customers, rude fucks.
