In my opinion, above a certain size, companies don't really care about employee quality all that much. So long as they meet the initial hire criteria it doesn't matter who's a 5x or 1x dev anymore. It's just one FTE anyway in the planning.
At this point the company has become a bullshit churning machine whose effectiveness is measured by its rate of churn. They milk cash cows that gained traction in decades past, while most new work is just part of the churn.
