Why do you think that informal work is bad? All the tasks are different - who runs away from alimony, who does not want to feed their taxes, someone needs to do so that there are no extra records in the workforce, and there are few reasons.

Father, well, you said everything, you detailed the tasks. Maybe you can make conclusions yourself, without clues?
Probably in vain, we now do not put a job place in the passport. Or all kinds of judges call on my taxes an ambulance, badly go to the clinics with the whole family, receive subsidies to pay for housing, as non-working, teach their children in schools, retirement will then be demanded, the parasites of society.
