The technology sphere is one of the few in the US economy that is still fully functional, dynamic, often fast growing, highly innovative, and wildly profitable. It's also one of the few in which you can still get very wealthy starting from very little, and do it fairly quickly.
The parts of the country mired in perpetual erosion, from Detroit to Baltimore etc, are extremely envious of Silicon Valley. The truth is, Silicon Valley has separated itself off from the collapse that the rest of America has experienced, and it has been able to do so because so much of tech is still a free market. That free market has produced bountiful wealth, and outsized influence that goes with it, while much of the rest of the country has stopped producing new wealth.
There simply are no other fields in which I can spend $100 tomorrow and set up a new business (AWS, or a dedicated server, and off you go). I need no permission. I need no lawyers. I need no zoning permits. I need no environmental studies. I need no retail space or warehouse. I need no tv spot, newspaper ad, or yellow pages placement. I need no consultants. I need no incorporation to get started. I don't need an army of workers. I don't even need to buy any software. I'm limited only by ... me. Oh and I need a $150 Windows XP machine with notepad and a free copy of WSFTP from 1997 that would run equally well on Windows 95, with a shitty $50 17" LCD monitor - and most of that hardware you can pick up for free from lots of sources.
