I have some experience building enterprise software and I'd have to say the problem was that it is mind numbingly boring to do. A lot of it sucks, so to speak, because people can't stay motivated to give a damn. It's pretty soul crushing to spend all of your working time building systems for inventory management, or AP/AR, or whatever mundane (but incredibly important) business function you're working on. This is why people make startups I suppose. I agree that, if you have the mental toughness for it, enterprise software is a GREAT way to make money. During my days of having a real job, we were selling our software for $250,000 an install.
