If any of that cohort of most tech people has enough money left over to pay off my mortgage, I'd be open to that. But I'm not a member of that hallowed club.
If you are not a member of the tech club then you don't have the tech risk. So, yes, while that may mean it will take longer for you to pay off the mortgage without a high tech salary, you aren't under the pressure that necessities the high tech salary to get the mortgage paid ASAP.
