That's the real problem here. It's extremely hard to make a living working for yourself anymore. Consolidation (resulting from crony capitalism, i.e. corrupt government) has resulted in a market where even if you have plenty of capital to start your business and manage it into great profitability, it's still a matter of luck whether or not one of the two to five megacorps in your field decide to move in on the market you've built and undercut you selling at a loss until you go bankrupt (and then go back to charging twice what you did.)
