The basic premise of capitalism is that the guy with the capital takes both the financial risks and the financial rewards. Labour prostitutes itself to capital for the best deal it can get. The government sets and enforces the rules of trade (ie: the "market"), some are closed markets (eg: plutonium market), others are "free" for anyone to participate (eg: NYSE). However without government regulations (in particular property law), there is no "free market" or any other kind of market, the entire edifice simply collapses back to the default system of trade - anarchic barter.
Domestic laws and international trade agreements are the "mysterious force" that motivates the "invisible hand" to move in a particular direction in search of profit. Unfortunately for most of us that direction has been towards greater income inequity for the last 4-5 decades, so much so that the world's richest 500 now have a greater combined net income than the world's poorest 3.5 billion, to put that number in perspective there were only 3.0 billion people alive when I was born..
The "system" can and should be changed to one where labour is actually rewarded and the difference between riches and poorest is one or two orders of magnitude, not the current six or seven. How this can be achieved I have absolutely no idea, all the other "isims" are just as bad, if not worse. For instance Karl Marx starts his manifesto with the words "To each according to need, from each according to ability", it's a really good opening line that is hard to disagree with without looking like a sociopath, but it goes down hill rather rapidly after that first sentence.
There is however hope that the pendulum might swing the other way. This whole (modern) democracy thing can be traced back to a group of wealthy merchants forcing a warmongering English King to sign the Magna Carta. Wealthy merchants today also have the upper hand with the current globalization thing and wars are bad for everyone except those in the (closed market) international arms trade. Many of the really big multi-nationals have openly embraced moves like the Sarbanes-Oxley act in the US and anti-corruption laws in the UK/EU. I'm sure like me, many people here on Slashdot have to suffer mandatory "corporate governance training" as I do once a year to officially remind us these laws exist and apply no matter where you do business. But at least it's a serious attempt from the "big end of town" to move the invisible hand in the right direction. - Assuming that you think enforcing the same basic market rules no matter where or with whom the company does business is a sensible step towards levelling out a very lopsided global playing field.
