"National Minimum wage increase is trouble"

That's actually part of the problem.  Nobody is begrudging someone, who is worth it, getting more.  But to give someone more just because they do not have the ambition or skill to do anything but minimum wage jobs is not the correct thing to do. Yes,  there are people also that will actually do the minimu wage jobs better---and they will do it for less also!  Sure, someone may do a higher skilled job better.  But eventually supply and demand will dictate that person will get paid more.  Unless, as you imply, money doesn't mean that much to them and they 'settle' or are okay with getting less than they deserve.

You mixed in a couple of things there and assumed a couple of things that are not always true to imply the MW should be raised.  But it becomes a cycle then.
