I certainly agree with that, they may have the brains but the people with the brawn should get paid a fair wage, how you work out what a fair wage is I don't know.
I think most agree, but this is embedded all over capitalism across the majority of entities. If you own a business you get the perks but also have the risk, if you are a CEO you get paid a lot for "thinking" and "managing" people, those grunt workers can get paid a small amount for doing very demanding work, it is how the world is, it sucks and its a reason why I work for myself now. Uber drivers in Leics are clearing £100 a day, which I dont consider a low income. Especially for Leics which has the lowest mean income in the UK.
Another thing to consider with uber drivers, is because its all digital, they are forced to declare all earnings so no tax evasion, whilst any cash in hand job tax evasion is rife.
