Of course, what you are considering could involve jail time, the loss of your children, and the seizure of your property if the laws of your state allow for it - especially if revenues from an unlawful business are used to pay for the property.
On the other hand, McDonald's is LEGAL work, even if not the greatest job or career potential. ANY work is better than NO work. In fact, I just came from a class at our social services agency where they are learning how to get jobs and how to live better, and one of the subjects that came up was precisely this - getting a job that was either "beneath" you, or, a job that paid less than you wanted. These folks would be happy to get a job at McDonald's.
As one of my neighbors put it to his son-in-law who was explaining why he turned down a job ...
SIL: "Pop, it only paid nine dollars an hour."
POP: ... Long pause and a slow nod ... "And just how much are you making right now?"
Any lawful work is good work. If I had to feed my family I'd be taking any job that I could, not one that could get me tossed in jail, would expose my family to unseemly activity, and one that could potentially cost me everything I own.
I know times are hard, but there are options - you just have to plug away and consider all the LEGAL possibilities.
Good luck.
