I my country too there are rules to have continuing training throughout the whole professional life as a psychotherapist. But having good training is another issue ... one would have to pick good quality training programs and also really learn something. A lack of ethics is indeed a matter of education and that can be fixed, but it can also be a matter of lifestyle and personality traits and that would be better addressed in personal therapy than in training, I think. I think a combination of ongoing therapy/training/supervision is optimal, but with so many different standards, licensing bodies, associations, schools, etc, I find that the formal requirements can be evaded by those who aren't truly motivated to do their best and keep growing. I think it's a sad reality in some cases.
