> I’ve often wondered why governments don’t provide a ‘dating’ service for employers and employees, or even better some kind of career development and management service for citizens.

Don’t they? Here in the UK at least participation in programs like that is a requirement of unemployment benefits. One has to attend a job center where one is given advice, sometimes training can get enrolled in trainung and etc. Not saying that they do a great job of it but they seems to at least try to do what you describe. At least nominally.
