1 - Honestly, I am not sure for the case for the UK, but where I am from, our rural communities do not really have large amounts of employment (or ties to the land), so like, I am not sure if this would work in the UK.

3 - It is not a matter of those who work harder, it is a matter of those who have more money, and thus do not have to abide by the law as strictly.
4 - Yes. All drugs
5 - I know it seems absurd, but I wanted to make it as a "boost" for experience. Where I am from, we have a lot of people working minimum wage full time while supporting a family without the time to go and get an education, so I just wanted those kinds of people that stay in minimum wage to be paid more.
