What a crazy idea! A legally mandated minimum wage, no matter what the job or the interests of the people involved! A hangover from the baronial union rule of the 1960s. Get rid of it now. It would do wonders for the black market, too.
There are lots of people that would like to have a part-time, even if low paid, job to give them something interesting and useful to do and some pin money. Bring back the car park attendants and public toilet supervisors! Someone to sweep the platform at a country rail station – the unions have stolen these people's lives and made car parks, stations and public loos a nightmare, sometimes even leading to closure.
