Oh come ON!
Walmart is only around now because it has DESTROYED competition through any "legal" means necessary.
We all know legal does NOT always equal moral.
They would do things like the following:
Find a supplier that sold widgets to several different distributors. They sold a total of 10K widgets per year at $1 apiece.
OK, Walmart comes in and says "We want 14K!". Wow! Great! $14,000!!! Christmas party! Oh, but we can't supply our other distributors.....
Oh well.
2 years go by and WalMart says, "hey, we want to do 15K this year, but we will only pay you $13,000".
??!?
You want more for less? Fuggetaboutit!
The widget mfr then goes back to their original distributors, but nobody wants to buy them. they found other suppliers and, at best, would only be able to buy them at a smaller volume than before for the next season.
So, this company is now locked into supplying WalMart.
The same thing goes for their leveraging lower prices in a neighborhood by taking local loss, and having a crew of "professional" staff when first opening.
Once the competition is gone, the prices creep up to national average and the crew gets swapped out for cheaper locals (Home Depo does this too. I have seen the degradation in staff between a new opening and a place that has been around...)
They are just NOT a good example of how Capitalism should work, or what we should strive for.
As for the people saying that these poor should invest, it is easy to say $20 is nothing until you see how much beans and rice that pays for.
So, having someone (with no real internet access, market knowledge, or technical knowledge) go in and invest in shares in a stock they do not know about, to wait around 15 years to see any real profit from, is not realistic in the slightest.
Hell, even people that were given company share as a part of their compensation package were easily screwed as the company issued more stock and essentially devalued any shareholders piece of the pie.
It is all a game, and those that make the rules will get as much as they can without the mob going bloody on them. The problem is, they have gotten pretty close and, combined with a lingering recession, may have stepped over the line of tolerance a few times.
If they do not watch out, we may see an actual bloody revolution as the number of hungry exceeds the number needed to break societies social "discression" boundaries.
