And yes, economics is a social activity. One that includes more than those employee's. It includes every single person alive. But like every social activity there is always those on the top, and those on the bottom. That will never change and is impossible to get rid of...even with unions.
Lets look at it this way. Does the individual employee have to pay any other employee? Does the individual employee have to pay the manufacturing costs? Does the individual employee have to pay the electric bill? The permits? Does the individual have to worry about whether thousands of products will sell or not? Does the individual employee have to worry about negative publicity that could loose customers? Does the employee have to pay for the products that are bought wholesale? Does the grocery night stocker have to worry about making sure that the electronics section is stocked?
I could go on and on with that list. But in all of them the answer is No. The employee does not have to do any of that. The only thing that the employee has to do is do the ONE job that they are assigned to. The one job in hundreds that are required of such companies like Wal-mart. The owner of the company has to make sure that all of that is accomplished. He/She normally does that by hiring other people to make sure its done. But if its constantly not then it must be brought before his/her attention so that he/she can remedy the situation. Along with remedying the situation that made that situation get all the way up to him. (just one small example of how a CEO's job includes more than just controlling capitol) A CEO has to worry and take care of the whole company, the individual worker that you are mostly talking about only has to worry about one thing.
So, with that said...why should the employee, who again only takes care of one small detail among hundreds, have a "right" to dictate the wealth that his/her already compensated work goes towards?
