And when the job market for developers is no longer so hot (bound to happen eventually), guess whose resumes are going to the bottom of the pile?

Never forget that what goes around comes around.

It sounds like you hold a grudge against people who would rather switch companies after 2 years than sacrifice large amounts of money out of some misplaced sense of loyalty.

Loyalty? Thanks for the laugh, mate. Nope, it's just dollars and cents.

It sounds like you think employers should be happy to be somebody's stepping stone and eat the cost and man-hours of hiring a new employee to replace them before they've even contributed enough to break even on their own hiring expense. Funny how hiring managers somehow don't think being stepped on is a good deal; gosh, I wonder why?

> eat the cost and man-hours of hiring a new employee > it's just dollars and cents.

A monetary decision was made to terminate my business relation with you... a box will be provided for your tears.

Can't terminate a business relationship when they were never hired. No worries and no tears.

THIS.

You'd have to be stupid to stay longer than 2 years if someone is willing to throw a whole lot more money in your face.

I agree, but that's going to run out eventually, then you're in trouble with your list of 2 year stints.
