Well if you close down all the money laundering shops then those barbers won't have jobs anyway, will they? So they'll still have to go home if they are not British nationals. How many of these places do you see employing British staff? How many of these Turkish/Kurdish/Balkan men were even in this country more than 15 years ago? I'll bet hardly any.
If the government got its act together and closed these places down, then the employees simply aren't needed. We don't owe them a chance to go self employed. There are obviously far too many of them and they could not feasibly all make an honest living. Every man in the UK would be having to have haircuts weekly for that to make sense. Somehow, in the past, we always managed perfectly well with just one barber in each small market town, not five...
It's the same with the Vietnamese nail bars and the Albanian car washes and the Romanian Big Issue sellers. These people knowingly allowed themselves to be trafficked to the UK to work in these money laundering places, or somehow linked to organised criminal gangs and scammers of the system. They are not naive, they know EXACTLY what they are doing, most will have paid a fee for the privilege of being 'trafficked.' I am not interested in whatever 'difficulties' they allege they might face against the local 'mob' if they are sent back. It's not my problem, it's not my country's problem. They got £££ signs in their eyes, took a punt on something dodgy, it didn't work out. They should have done their own risk assessment before they signed up.
Close the places down, send the staff home. Every honest, hard working, legitimate barber and nail technicianin this country who now struggles to stay afloat because of this dodgy competition will thank you for it.
