> you can't replace Ronaldo with any number of cheaper footballers
Of course you can. It's a team game. Having Ronaldo wearing your team's shirt doesn't guarantee a win. So a team of 11 cheaper footballers with a better plan and coaching has often beat whatever team Ronaldo plays on. "Cheaper" != "cheap" of course; they're still immensely talented and well-paid athletes.
What I mean is there's only eleven slots on the field. You can't swap one star player for a hundred mediocre ones. It's worth seeing which industries do and don't work like that.
