You own it if you own it, keep your personal investment at arms length, lest you become a Jason Bateman character desperately putting in those extra hours so one day hopefully you'll be blessed with that VP position or w/e.
That said, of course if you've achieved something within a fairly tight constraint, ideally you're compensated or recognized somehow for it. Extra worthwhile hours should also be compensated for obviously. But if nobody is willing to pay you for it, it's probably your own undoing.
What I am saying is that value in a product can be "discovered" along the way. An engineer that demonstrates how to add value through individual efforts will probably experience burnout if management chooses to ignore their efforts. But more mature managers will figure out how to work with it.
Management that denies engineers this sense of ownership and achievement is a likely cause of burnout. I think we agree mostly agree, but in my view management shares responsibility in this case.
