Doing the same job as someone who has paperwork, just without paperwork, isn't unethical. Real ethics have little to do with arbitrary regulations made up by men. I don't consider people like Edison or Franklin to be charlatans because they lacked formal education. I wouldn't consider it unethical for Franklin to teach electrical engineering to somebody because he didn't have the formal education of others. If you do, crack on mate.tMy point's made.
Keep picking, if you you've got an itch, essex.
No idea what your Essex comment is about.
