In terms of how easy it is? Well, I dunno, I personally find animating and drawing something easy to do, but mostly because that's what I'm passionate about and have been practicing for years, but in terms of how much income you'll get, I would say a lawyer or a medic, those are not easy jobs at all, in fact some of the most difficult ones, but also some of the ones that pay the most. I personally want to be a doctor since I love medicine but seeing it from my fimily's perspective, I want to be a lawyer, since most of my family are succesful lawyers. Anyhow, easy doesn't mean better most of the time so I would go for something you are passionate about instead of something "easy that pays well"
Probably being an editor is the easiest job. IF you are well known and good at what you do, you can easily make top dollars by being hired by high up companies.
