Parents are the biggest culprit. In a bid to make their child score high marks, they are willing to indulge in practices that are unethical, like buying projects. They do not realise that such attempts will not make their child brighter or think over ideas.
Good teachers must inspire children to work hard - make projects and give them good marks even if genuine projects look crude and unprofessional.
