The worst misnomer I hear is always that somehow these companies are there because of the government. Remember "You didn't build that?" This is downright disgusting.
Let's take a look at one product:
How about insurance companies to make sure the company has work comp/health insurance/etc? The myriad of employees who do sales, manage accounts, HR, IT? The various companies who do work for Heinz for everything from repairing their IT equipment to providing them with phone and data lines? More trucks to deliver means more gas being sold, helping the gas station. Those drivers get paid and they in turn are buying various products.
I can go on like this. One lousy bottle of ketchup creates so much ongoing economic activity, it's staggering. Now put that thought exercise to a company like Wal-Mart.
But all of this can be quickly curtailed or undone by a government that creates too many regulations, and forces too many taxes. And unfortunately libtards, the government regulations and taxes have become insane. So the liberals who hate the giant multi-national conglomerates and rail incessantly that there's no way for a small company to compete, well blame yourselves. Because trying to create a business that abides by all the regulations requires an insane amount of capital now. The only companies that can continue are the giant multi-nationals you say you hate.
The next time you you hold a bottle of ketchup in your hand, or any product for that matter, try and think of all the jobs, direct and indirect, are created just because you and many others bought it. Your cheeseburger will taste better.
