What, you'd have to pay $12/hour to find someone to shovel your pig sh*t in 110 degree heat, and you think that's too much? Then, by all means, do it yourself.
Globalization has changed all of that. Look at Walmart, if you have an item that you would like them to sell there is no negotiation. They tell you what you have to sell if for which then makes you go back to your manufacturer and pray that the item can be made at a reduced amount. Either way we are screwed. Look at all the mom and pop stores going out of business. They cannot compete with the cheap labor that Walmart uses and that gives Walmart unbelievable pricing power.
