Since our employers are clearly not above playing juvenile dirty tricks, what's to stop us engineers returning the favor? Other professions (Doctors, Lawyers) use legislation to restrict the supply of labor and drive up prices, so why should software engineers be any different? We currently make ourselves vulnerable to manipulation and abuse in a way that no other profession has been stupid enough to do for centuries. We should lobby aggressively for legislation requiring professional accreditation for practicing software engineers, as well as for the provision of training and documentation services. We need to shut down the technical MOOCs, as well as efforts like stack overflow and code academy. All of these things, whilst seemingly noble, do our profession grievous harm.
