The fact is there will always be a need for menial, less exotic jobs. There will always be someone who has to do it. Is it fair that they should struggle because the government feel these roles are not worth paying a living wage for? Why is a person seen as somehow deficient if they do not have ambition? Many people are more than happy to do the same less exotic job for many different reasons. Perhaps because it is less stressful, perhaps because it fits in with their family life, perhaps because they have no real ambition. The country needs these people just as much as it needs the people at the other end of the spectrum.
If they dont want a more demanding job, they need to accept the job they are in will not be as equally rewarded as one that is more demanding.
