Maybe not when you put it that way, but small businesses used to be a larger share of the economy and a more viable "rags to riches" path than they are today. The system is undoubtedly rigged to favor large businesses - most people understand that intuitively but the anti-trust cases the government is currently prosecuting and in many cases winning are hard evidence of how the US really punted on protecting the small businesses from the big ones over the last few decades. You aren't going to find many people in the working class who disagree with the idea that big corporations should be cut down to size and we should have an economic system that's friendlier to people who want to be their own boss.
