It happens temporarily all the time of course such that there are plenty of talented people underpaid at a given time but long term most will not be. I along with friends went through bouts of shitty jobs, but it is rare to stay that way. Hiring from the pool of low rate workers is not a suitable standard practice at a place that isn’t a shithole.. as we see here with Intel.

People get paid what they ask for. No one is underpaid or overpaid.

Simply ask for more in salary and benefits. When they ask why, state all the reasons why the increase is warranted. If they deny the request, look for another job that pays the higher amount.

Yes, your first job. Not your second. You need to be deeply unpleasant to work with for no one to tell you you've been exploited when you leave.

He probably told you that because that was the minimum salary range for that position.

Then that underpaid employee gets easily poached for x3 their pay a year in, when they have all the valuable knowledge and work responsibilities.

Sounds like what happened at Intel, from the top comments.
