Not everyone has the skill, commitment and ,yes, money to compete at the National/Majors level. Your "It's called competition. Get some." comment is far more condescending to regional racers than anything I've seen from the PTB in SCCA. ...
How is it condescending to "regional racers?" It's supposed to be condescending to anyone who chooses to avoid competition.

Atlantic coast Regional ITB races used to be WAAAAAAY more competitive than a majority current Majors class races are now. The guys who won my two-car STU races in 2003 didn't in my eyes have much to crow about. And I'd say the same to those who cherry pick poorly subscribed SARRC races to win a "championship" against racers they never see on the track, let alone beat.

As to why consolidation? Look at SCCA's closest competition for a great example.
