impelse is on the money, here. As with any certification, the pay is always commensurate on the proven experience. You MIGHT get lucky and land something high-paying, simply by showing the cert, but if you start working, and can't perform as expected, you're likely to either be let go again, or have that Porsche and high salary taken away from you, or lowered. I think for any instructor to make that type of comment, they are biased towards what they're teaching, without first understanding YOUR capabilities and retention skills.
Additionally, a RH person, who knows RH, is always more likely to propose the value of RH, versus another distro. Same for a SuSE person, or an Ubuntu person, etc. It's all in the flavor you're accustomed to using. Mind you, RH has the larger market share for the moment (but it is beginning to wane a bit to other distros,) but ultimately, if you have ANY Linux cert, and can show you understand it as well as some RHCE who has his cert 'on paper only' (meaning he passed a test, but doesn't retain the knowledge well, afterwards,) then you could still land that high paying job, and get your Porsche!
That said, I'd also agree with KamiCrazy's comments, that while RHCT, in his case, might not be something he uses, day in and day out, he noted the benefit it gave him, in using tools and distros, such as using BackTrack for his OSCP, and that fundamental, underlying Linux knowledge goes a long way to helping you do other things.
My full-time employer stresses Linux, and went as far as switching 80% or more of our folks to Linux, in a single year. While there are still Windows folks in the mix, where they need to exist and use proprietary software and tools, it was amazing how fast certs like LPI's LPIC-1 came into play, in helping ourselves and our coworkers with day-to-day work. The ONLY primary difference you'll find between distro's is some minor changes in the filesystem locations for things, etc, but ultimately, if you understand the OS, itself, those differences are easy to overcome and work through.
Good luck, and let us know how you do with your RH certs!
