Are Barriers to Entry a Problem?

The worst businesses are ones that have high barriers to exit, because they can't get out of the industry. Egsit in terms of how long lived the assets are, where, if you have short life span assets, right, where it's all piled up in inventory and stuff, then that can fix the industry much faster. The point at which you would actually shut things down is very am low. I don't know why the economics would be that different from when utilities were a growth business.
