The other way I've earned significant compensation is by being hired at a senior level, a VP of Dev or really any very senior technical position. At a company with money, these roles can easily make $200k in base salary, and much more with bonuses/equity.
The thing to keep in mind I think is that inflation is a very big factor. Making $120k in 2003 is effectively the same as making $150k in 2013. The numbers keep getting bigger, so $200k salaries really aren't that extravagant.
And it doesn't matter how much you make if you don't save. Plenty of $200k earners save less than $100k earners do. Anyone who can save $50k/yr is going to be a very happy camper in the future, and most young people could easily do that on $120k if they wanted to.
