Before we even begin the debate, I think it's pertinent to understand that Capitalism didn't even have a name until people such as Karl Marx tried to criticize it. It is a natural law, comparable to gravity, which is why Adam Smith called it the "System of Natural Liberty". You don't hate liberty, do you? Capitalism can't be disabled or outlawed and neither can gravity. Trashing this natural law is as nonsensical as complaining about the speed of light. A true progressive would study this phenomina and use it like a tool to build a better society (I respect many opinions on the role of government concerning this application- I'm not arguing for unrestricted capitalism here). The world is not flat, and the free market plays a vital role in allowing for our society to be so complex. We don't have to make our own soap anymore thanks to capitalism. You could if you wanted to, but Irish Spring is just fine for me.
The idea of free trade on any scale of economy is as old as society itself. A farmer would trade food for tools, and a blacksmith might trade tools lumber or medicine, etc. Bartering is excellent free trade, but nothing promotes liberty like the endless flexibility of currency. Not everybody is a blacksmith, farmer, or a miller, so bartering is limited by the relative value of their goods to customers. Currency allows a coal miner to buy a Megadeth T-shirt from California.
Currency is simply a means of settling a debt between people. The US government devalues our currency by spending more than they collect, which causes the same damage as counterfiet currency. The problem is not currency, and the problem is not capitalism. The problem is irresponsible makers of policy with no respect for the natural system we call Capitalism.
Our stock market is legalized gambling, to be sure. Stock prices are set at around 20-25 times the earnings of the companies they represent. They are extremely overpriced, but historically this works well enough for people to trust their life's funds for retirement to. Even being so overpriced, I know that the returns from stocks and bonds will be far beyond what the Federal Government will ever return. Do you honestly think those clowns in Washington care about our retirement? They'll be long dead by then, after living a life of wealth and influence from the money they steal from our paychecks.
Furthermore, if you want to "take the power back", save your money and buy stock in these giant corporations that everybody loves to talk shit about. When you buy stock, YOU OWN THE COMPANY! It's difficult to own significant portions of super-huge companies like GM, but some people do. If people would stop buying stupid bullshit like new cars and expensive clothes and instead focus resources on buying back the companies that we feel are on the wrong track, then the "people" would have a voice, and would have "taken the power back".
You can take control of our corporate culture, but it will require the sacrifice of the MTV lifestyle. People that buy things on credit cards are signing themselves up for slavery. Who do you think pays for those skyscrapers in New York with "Chase" and "Citibank" at the top? Fact: the borrower is servant to the lender. Buy stock, and they are your servant. Buy stupid bullshit to impress people that you don't know on credit cards, and they own you. Credit card companies have so much power to buy off politicians, and it IS OUR FAULT. We give them that much power because we owe them too much money (collectively). We don't have power, we "have it now", and we'll spend our lives trying to pay it back.
It's so easy to bitch and moan about how rich some people are when we're doing nothing with our checkbooks and votes to take it back. Those people at the top are not stupid, and they know how to get you to keep paying them money so you'll never get traction for upward mobility if you choose. Capitalism is like gravity, we have to understand how it works and use it better if we hope to overcome. As for me, I'll learn as much as I can about our markets instead of complaining about why we can't fly. A war on Capitalism is just as laughable as a war on terror, drugs, gravity, and procrastination.
