That doesn't mean that moving up that hierarchy is not desirable. Whilst a life of crime may offer an escape route from a life of poverty, there are benefits to society at large if other escape routes out of poverty are within reach. If opportunities are not made easily available, it's up to the individual how much work they're willing to put in to make opportunities for themself. 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.
