To be honest, it's hard to believe that people can be either so gullible or so thick that they can't see what a load of empty drivel such statements are.
The same is true of the 'you should upskill/ get a better paid job' .
Those who are able and get the opportunity already do that, but even if it were possible for everyone to do that - which it clearly isn't - the the country would quickly be in even deeper sh* than it is now, because there would literally be no one left to do all those low-paid but essential* jobs The country would grind to a halt.
No job , however unskilled it is, should be so badly paid that someone doing it full time cannot afford a basic standard of living.
