>> MechE are probably only 20% of what you'd earn studying CS Maybe if you are a MechE working for facebook or twitter. But go to something like SpaceX or BMW and you will find the best MechEs paid way more than the software people. The insane paychecks in CS only exist at companies where software is the final product. Companies that produce physical products put CS into a support role. A department head at Boeing or LM is far more likely to be from an engineering background.
