I believe you when you say your efforts are needed - the problem is management very frequently has a hard time being able to understand that there is an upfront cost that will eventually pay off. They are looking at spreadsheets and just want to see that profit column keep on going up - you essentially are proposing that the profit column should go down a bit (development costs) with the promise that it will eventually go up much faster.
I've found that software companies either qet the necessity of quality/process or don't (also some types of businesses do not really need much software quality). Most of the time this is determined by if they have technical people in the leadership ranks or not. By the hiring practices you listed Im guessing they don't get how software quality and process impacts the bottom line.
My pessimistic view is that very little will change with the exception of burning yourself out - sorry for the dire prediction Ive just been there myself.
