If you feel guilty enjoying the product of your work, you were probably doing pointless zero-sum work that did not need to be done. It is fine to say you want other people to be economically empowered, but the amount of guilt flying around here is incredible. Why not apply the constraint of only doing things that actually benefit other real humans at the start of your career, and feel good when you end up being successful at whatever constrained but moral venture you undertake. Feeling guilty about it accomplishes nothing. We made the collective bargain to build a technological society, we cannot go back now. Fix the real problems and it won't feel dirty.
