The problem is'nt as simple as companies or individuals making vast profits in an unethical manner or not. It's rampant speculation and manipulation by hedge funds, banks and hoaders. For example, a hedge fund in London recently purchased 10% of the worlds cocoa supply and warehoused it, in order to escalate the price by causing a shortage, then sold for a huge profit, this is only one of many such practices, the major speculators on the worlds stock markets use super fast computers that buy and sell huge ammounts of stock in a split second, the average day traders and casual players don't stand a chance anymore.
One of the more ominous problems, seems to be that some corporations and financial institutions are favoured by TPTB above others, when it comes to regulation and scrutiny, Wells Fargo and Bank of America, to name a few, have both been caught red handed numerous times, found guilty and fined for laundering Mexican Drug Cartel funds, and when the bail out of the 'too big to fail' companies took place, certain businesses were abandoned in favour of others without a reasonable explaination.
Ask yourself, how can an average person become a member of the house or senate, and within a few years be worth millions, on just their salary alone.
For regular folk who have no insight into the 'closed door' dealings of the lobbyists and huge campaign contributers who donate incredible figures by proxy, to avoid the legal channels, think everything is above board and done the proper way to benefit the citizens, when that's further from the truth than people can imagine.
