After 20 of years in the industry (mostly GA) I can say I loved every minute of it. The shortage of engineers will only get worse for at least the next 10 years thanks to the retirement rate and lack of new people coming in at the bottom. Even bend a lots "minimum LAME wage" of 64k PA is above the average national wage.
