Who do you think is more likely to be incompetent, the board of directors of McDonald's or 10 employees chosen at random throughout the entire organization?
Sure education isn't everything. The average mcds employee is a good person trying to earn an honest living fit to have a beer with but probably not the best source of sound investment advice.
Put to a vote they would all vote to raise their wages to 15/hr and the vast majority would be unemployed in 6 months because I'd be able to get a better burger somewhere else for less money.
Lets use the fishing boat analogy. So a fisherman fishes for 10 years saving his pennies and investing and builds a fishing boat with his bare hands. He (The captain) then hires 3 hands to help him run the fishing boat. If everything simply came down to a vote there would be no incentive for the captain to save for 10 years and build a boat.
If the 4 fishermen had all saved their money together, and pooled their resources to build the boat equally, then they could have equal say in how the fishing operation is run.
When I ask my friends who lived there during that period they unanimously proclaim how much better life is now and how the standard of living has dramatically improved. Many more people can afford cars and there is incentive to work hard.
