Now, this is what's interesting to me, because on some level I agree, and on another I disagree. There are many people I'd consider pro-level players who are doing occasional gigs for little to no money now, because nowadays that's all there is. But that situation has also allowed a lot of true hobbyists to enter the arena and strut around. Again, we're talking about "players" who can't stay in tune, can't solo in the correct key over changes, can't sing a harmony, stop songs in the middle, etc. All stuff that, in my day, was unheard of among what we considered to be professionals (well, maybe not the harmony thing but it was a lot easier back then to find singers).
In general, I find the level of quality in live performance, at least where I live, to be greatly dumbed down from where it was 30 years ago. There are exceptions to this. There are bands out there with great players but they are not the rule. So I contend that the lack of value appropriated toward music has created a situation where non-pros can get gas money but real pros can no longer make a living wage.
