I wonder what a Concorde Pilot made?

Depends on what training you choose.
I know schools that will get the job done from no experience to first officer in a Beech 1900 in just 18 months.
you can also go via Universities (get a degree while you get your licenses), and that can take 2 to 4 years.

However, remember that you will be a FO...to be a captain expect some years as First Officer (2-3) and this is just for the aircraft you are currently rated on
When moving up the ladder you'll first be in the right seat - again 

Thanks,

Just wondering if this would be a viable future career path if I ever get sick of what I'm currently doing.  Maybe if I ever want to go in to super-semi-retirement...

Starting from scratch $50k is quite a reasonable entry cost in to the profession.  It's about on par with what a lesser private university would charge for a Bachelor's degree, and it sounds like pay would be similar to a typical starting pay for the holder of a normal Bachelor's degree.
