If that is available to them, then they have absolutely no incentive not to take advantage of it. As long as a set of inperfect rules exist rational actors wil exploit those rules.
Now, i know what you will say to this. Wal mart made those rules for themselves. And they did. This is why they arent capitalists. The issue with the wal marts of the world( wal mart i really just dont see as that bad), the exxons, the GEs , etc. Is what can realistically be done? They accumulated power through what is seen by the public as legit means. Their shyt cant just be confiscated.
This is why the public corporation was the best idea elites have ever had. Thanks to that and 401k plans regular people have a direct stake in the success of these companies, so they will never truly oppose them. Young people dont own stock, so they feel comfortable trying to take them down.
Wal mart provides absolutely nothing of value as far as I am conerned. They are a gateway to china and promote mindless consomuer culture. But in a world in which rupert murdoch is one of the ten richest men, we have endless war, pollution, starvation, lack of clean water, etc. I cant be mad at wal mart. They have low prices and hire/promote black people. What else can I ask for?
