Two factors to consider: Location and risk/reward ratio.
The "$200,000" figure -- as mentioned earlier in the discussion -- is extremely location-dependent. Let's say you live in Salt Lake City, UT and make $100,000 per year. I'm from the area, and $90K-$110K seems to be a very typical pay rate for sysadmins and programmers with 10 or more years of experience in their field, if you include health and other benefits in the W-2 (all the employers do!). Then let's cross-reference that with the Cost Of Living calculator at http://money.cnn.com/calculator/pf/cost-of-living/ . To enjoy an equivalent quality of life, here's what that guy needs to make (these are all area averages, not the specific cities referenced):
San Francisco, CA: $171,987
Los Angeles, CA: $140,380
Seattle, WA: $123,784
Raleigh, NC: $99,154
Austin, TX: $97,991
Washington, DC:$151,479
New York, NY (Manhattan): $231,289
New York, NY (Queens): $162,684
Advice for earning the big bucks? If you want to earn a high-end "salary", move to one of the technology hubs. Get an education in finance and high-end mathematics. Or get a security clearance, shine up your resume and skills, and plan to have no life outside of work due to travel abroad. Get some solid experience, get in on some high-profile projects, and job-hop when you're at the apex of your visibility in your company for much better pay.
If you don't want to live in Silicon Valley or New York, then be your own boss. Write your own products. Innovate in a field that lacks innovation. Develop software nobody has really thought of before. Monetize it and make a living. Cash out by selling the company to a bigger fish, and start working on your next idea. My company, for instance, buys small companies who create innovative software a LOT and integrates that software into its other offerings. And that strategy works very well for continually expanding the customer base and revenue. Sometimes it works out well for the little guy, sometimes not. It's a risk of running your own business.
Working for someone in a "typical" IT or software engineering field is typically not gonna make you rich. It can make you a good living with solid pay and far less stress than running your own business or working in high-pressure financial and security markets, though. And you're less likely to lose several fortunes on your way to making a fortune if someone else takes the risk, and you get paid the salary. Risk/Reward.
For me, quality of life matters a lot. I've been on both sides of the fence (trying to make it in business for myself vs. drawing a salary), and right now in my life it makes more sense to draw a reasonable salary doing a job that I love in a great environment working with quality people and making a positive difference without feeling that my job is my life. But I know I'm probably not going to strike it rich doing so... and I'm OK with that.
