Of course you can argue that as long as you have enough talent this doesn't matter.
But invention and innovation are wildcards, and you can't always create gamechanging developments to order. If access to environments and resources that develop talent is heavily rationed, you're more likely to get a non-linear collapse in output than a linear decrease.
