Depends on the type of work. Those working in agriculture and forestry are necessarily out in the country. And even the most remote areas need nurses, doctors, and teachers.
Again - nurses and especially doctors are going to be above average IQs - those people will do well whatever their profession in most cities with hard work - and I’d certainly hope teachers would be at least slightly above average and most teaching jobs require a college degree. What are you going to do with the other 65% of the country?
