Though simply paying more sounds like it would fix the issue.
No, what you have is a shortage of people willing to fill your vacancy at those prices.
Particularly in Perth there is a whole shadow economy of people working remotely for overseas firms, because local positions don’t pay the bills. This doesn’t say “shortage” to me, it says “cheap”.
And in the UK most small/medium businesses seem stuck in a vicious cycle of low pay, low productivity and low expectations.
Your point is valid even in the context of my humor actually. Many of these problems are highly local.
For example, the "shortage" of things in NYC are usually because people dont account for local constraints. My colleagues in NYC complain about a "shortage" of nannies, yet cant seem to see that the living wage in NYC is super-high. Why would a nanny work for below-living wages? I'm sure that with commensurate income, the shortage would disappear.
I think there are a lot of people who are going to school for animation, but maybe supply and demand are mismatched? But at the same time, a lot of VFX, animation and game studios are doing layoffs, so there probably shouldn't be that much a shortage of talent? I suspect GP comment may be right that the studios that are not able to find animation talent may just not be willing to compete on salaries.
