It was intended as tongue in cheek not a statement of fact.
The point is simply that the number of gigs available (at least here in the UK) is constantly dwindling. Most of the pubs that still have live music are still paying the same amount per gig as they were in the 1980's. That part isn't a tongue in cheek joke unfortunately. In Scotland pub gigs are paying around £300 - £500 for a full band, with all their own gear including PA, doing a couple of hours with a break. Of course there are more professional gigs and corporate work the competition for them is high. The days of the weekend warrior pub circuit which a huge number of semi pro players used work regularly or cut their teeth on before moving unto a higher level is dead and buried over here unfortunately. Live music venues are closing almost weekly. Even some great venues that have been going for decades have been closing over the last 12 months. It is tempting to blame it all on COVID but the truth is the decline was already well underway for many years before that. COVID just put the final nail in the coffin.Therefore, if younger players want to make a living from music they need to think differently and exploit different avenues and markets. I'm not being a grumpy old man shouting at clouds and ranting about how good things were in the old days but everything sucks now. Far from it actually. I believe there is hope for good younger players (and even old farts from my generation) but the opportunities are simply different. Trying to make a living/career playing live music venues (other than weddings and corporate functions) isn't worth the effort now and won't be in future unless the world changes significantly.
That is only what I am seeing here in Scotland and hearing from other parts of the UK. The situation may be very different in other countries though.
This is basically the situation in the US as well.
