Well look at it this way.
Gone are the days where producers could spend millions of dollars on a touring production (a la Miss Saigon, Les Miserables) and expect to gain a financial return. Because of the current state of just the touring market and such, the demand is not there. Sending a touring production of a Broadway show out to Yonksville, Nowhere proves to be a risky venture. I mean look what happened to Urinetown, The Full Monty and such. Audiences across the country are looking to spend money on things they are familiar with, which is why the movie musical conversion is going on right now.
The road isn't what it used to be. Producers are now forced to decide whether or not to send a show non-equity or Equity. If they do you use Equity actors, they would all have severely negotiated contracts (a la the last 42nd Street tour). So I don't know if it really makes a difference or not, but it just may be all in the eye of the beholder.
Look what happened to All Shook Up, it used to be a Broadway fave and now it's on tour but virtually disappearing and virtually scaled down to save costs.
In short, the road ain't what it used to be.
