While I understand your argument, it ignores the fact that, at scale, there is a non-insignificant chunk of society that is willing to break and bend the rules for personal gain, causing others loss, simply because that's the most direct path for them to obtain what they want. This is, at least in my opinion, exacerbated by the size and the diversity of the US population, and its variety of creeds, affluence levels, ethnic backgrounds, and others. The US is not Iceland, it's not Japan, it's not Finland.
If you increase the base floor of affluence in the whole of society, yes, people stricken by poverty will no longer have to conduct this kind of activity out of desperation, but many, driven by other impulses, will simply move up to a higher class level of antisocial white collar behavior, from scamming investors to conmanship et al. still eventually necessitating the intervention of law enforcement and jail time.
If you take a look at your average prison population, people incarcerated due to poverty-induced despair are only part of the picture. There are plenty of folks in there who, for one reason or another, spanning from genetics to growing up in extremely abusive environments, are not wired to succeed in society, and are in some form a menace to it, and need to be contained in a way that allows non-sociopaths to conduct normal living.
I can't tell you the exact desperation-to-sociopathy ratio of criminal activity, I'm not sure those numbers exist, but my hunch, based on whatever information I've gotten my hands on over the years, is that the sociopath percentage behind this sort of activity is non-trivial and cannot be simply glossed over in the interest of standing up for folks of lesser means.
Before we inject our own biases into this conversation, I would love to see the data, the stats, and understand why the culprits are doing what they're doing. Otherwise we're simply painting our existing moral and political positions onto this canvas with no way of refuting any of the stances. The trite and tedious unfalsifiable personal-responsibility-vs-oppressed-victim-of-circumstances debate that never gets anywhere.
