A point I haven't seen addressed is that in a lot of situations, to break the $100k mark in salary you have to move to somewhere with a higher cost of living.
I'm sure there are exceptions, but this is definitely true in my field (chemical engineering).
Smaller companies or those that operate in the middle of nowhere will often times offer less money because the employee will be located in an area where the cost of living is less.
I know I had to move from College Station to Houston to break the $100k mark. I would have eventually done it in CS (had the company survived), but it would have taken significantly more time.
But my 20% bump in pay came with a 30% increase in housing (for a comparable home to what I owned in CS). Not to mention the increases in insurance and taxes.
It was still a great move for me because my base salary has increased by another 40+% over 9 years (next year, including bonus, I'll probably come close to doubling what my salary was in CS), and I'm still living in the same house as when I first moved here. But I had to bite the bullet to make it work early on.
When I look at comps for my house in my neighborhood now, though, I would be close to being priced out, at least for my comfort level (I'm certain I could get a loan from a bank).
