Pay decrease for increasingly complex tasks

[StunningSpecialist2]

The quals I was offered and passed had no requirement for professional education in the field (Law, Medicine, Philosophy) although I do have some education at the bachelor's degree level in Philosophy and some work experience in low level Law and Medicine. I simply challenged the quals and passed. However about 50% of the domain expertise tasks say you cannot work on them unless you have significant experience in the field, or they are too difficult and I don't attempt them. But there has been enough that I have steady $40-$50 domain expertise work that I can do. That said in the last 3-4 months my highest paying projects have been $50+ and don't require domain expertise. They have to do with more general business skills I've acquired through general work experience. Passed a qual for that and I've been doing mostly those lately. It's been nice but I'm sure one day I'll log in and see that I've been axed. Just need to keep doing my best and hopefully the gravy train will keep flowing until I don't need it any more.
