As a starting point, there will always be people who are bad at their jobs. That’s not illegal, and a bit of inquiry will usually allow you to avoid those people (and hopefully the marketplace will eventually put the bad ones out of business). If it’s more than just lack of talent, people can always file suit for fraud, negligence, misrepresentation, and perhaps file an ethics complaint if that’s available.
IMHO, it’s not the government’s job to be looking over the shoulder of every professional. If the average joe would take appropriate steps when he/she has been the victim of something more than simply making a poor choice, a lot of the bad actors would be weeded out.
