So would I. But another way to look at this is, instead of "I'd quit", saying "they'd have to pay me 3x more to work in a place like that". At which point you can again start looking at it as an economic problem.
About the closest I've come to seeing any of these bullets deployed reliably is Microsoft's developer training and deprecation of the standard C library, and that initiative was so out-of-the-ordinary that it was newsworthy, and widely reported.
But to actually earn that bullet, Microsoft would need to deploy those same measures across all its contractors, and, more importantly, deploy them on internal IT and line of business systems, not just the Windows and Office codebases.
Plus, the posts I read earlier didn't mention 'Fortune 500' or 'reliably' - and I'm glad you didn't use words like 'productive' and 'efficient'!
