At one point in I, Milena, Milena's husband (who is a photographer) complained that someone had swindled him. When Milena suggested taking them to court, he said
What court, are you kidding? On what grounds? They paid me a bonus on top of the contract - threw me a bone, and now are free to rake in as much as they want... With the taxes we pay, if I were paid by contract alone, we'd have been looking in the trash for cans to recycle long ago!
What did he mean by this? What were the usual payment arrangements for contracts? Was it normal to expect people to pay more than the stated contract? Is this some form of tax evasion scheme? If so, how common is this type of scheme?
