Well, that was the other problem with the TIE/LN. It's average pilot wasn't all that well trained.Which is a different sort of penny wise, pound foolish stupidity, that is not even penny wise. Energy is so cheap that it is cost effective to haul grain out of gravity wells. Now all you need is a bit of time for the pilots to practice, and a bit of gear so they survive.
(I can squint and see the life support angle as mostly a reason for why TIE pilots won't survive long enough to take their craft and defect the way one could with an X-Wing. Come to think of it, wouldn't shields be necessary for operating in an atmosphere?)
