On the contrary - its precisely because these jobs dont generate direct income that the have to be paid from your taxes and therefore are paid less than positions in the free market where you can increase salaries of the most valuable positions to attract better employees and generate more profit.

But, as the others have probably realised by now, you will just rewert to your ultimate “you dont understand the term” or “your opinion is just incorrect” argument again. Alas this is my last comment in this pointless crusade - try to be thankful that the system works even though you dont fully understand it is my final advice (othervise the people working these unfarly underpaid social services but we doing manual labour by now).
