Not everyone has savings. Not every country has an extensive welfare system. In some places if you don't earn you don't eat. In those circumstances, are you going to starve or turn to crime just because you didn't want a crappy job?
The choices are simple.
Work at McDonalds/Walmart
Max weekly earnings: ~$420 assuming CA minimum wage and a 40 hour workweek
Smuggle cocaine from Mexico to USA
85k - 200k per run depending on quantity.
To be clear, I'm not saying that criminals are automatically bad, some have been faced with tough circumstances and are just doing what they can to survive, what I am saying is that we should encourage alternatives where possible, as society as a whole benefits when we offer other opportunities for getting out of poverty.
