Yes, I know quite a few that have capped already. Some capped quite young even. Lots of trades (plumbers, electricians, welders etc), teachers, ECE's, retail and service industries(managemen t positions, not min wage positions). When I worked healthcare, quite a few of those positions, especially management were at the top of their pay scale as well. After awhile, raises became less often and for many, eventually stop.
I'm sure different companies, especially private, are different though. Some offer more benefits instead of raises for example. I can't speak from first hand knowledge on all these positions but only from what friends and family have mentioned. Maximum wages definitely happen though!
