I don't think you should feel 'bad', but personally I feel extremely grateful and lucky to enjoy doing something that happens to be very marketable skill.

I often think about people in other professions who have to work harder in poorer conditions for less money.

For me, the best way to direct these feelings is to recognise I don't deserve this any more than those others in any meaningful sense, to try and live modestly and help out others to try and redress some of the imbalance.

The higher paid superiors are just more of a tiny fraction of the population who happen also to be in an extremely lucky position
