Deliveroo riders have some of the worst working conditions, it's a grind and people do it because they need the cash.

Going as far as circumvent legal regulations and even pay to be able to do such a job is a good indicator that the person doing it is desperate for income.

Many people believe wealth should be shared, that everyone deserve happiness, and that no one should spend their lives slaving away just to survive, those same people would not try to profit off of someone desperate for income and willing to work hard and would consider what OP is talking about immoral.
