No raise and afraid to ask

So I’ve been doin the IT thing for many years. It looks like the IT jobs pay ALOT less than they used to.

My company hasn’t given a raise in 4 years. So I’m still making above the job postings I see. Do I ask for a raise or keep my trap shut for fear I’ll get a pay cut?

What a friggin’ nightmare IT has become. I saw a college job posting. The post for a maintenance tech was the same salary as a net admin.
