My country may be higher-trust than yours, but my impression of how our social system works is that we've found it cheaper and easier to make social aid readily available, and pay a few people who double-check on recipients for possible fraud, than to pay many people to administer red-tape as a hurdle for social aid.
In any case, the immediate problem (at least going by the leaders of the UN security council permanent members), is not dark personalities claiming victimhood soaking the system, it's dark personalities claiming victimhood running the system.

Man looks down upon the speck at his feet called a microbe from an altitude of a thousand miles, so to speak, and regards him with indifference; I look down upon the specks called a man and a microbe from an altitude of a billion leagues, so to speak, and to me they are of a size. To me both are inconsequential. Man kills the microbes when he can?
He uses the word infinite. If the Lord is infinite, mathematically infinity divided by a very large number is identical to infinity divided by a very small number. So the microbe should get the same amount of attention from the Lord as the galaxy etc.
The argument only works if the Lord is not infinite but merely very very big
> Why focus on the individual instead of the environment that rewards him
I agree that we shouldn't stop trying to help people just because there will always be fraud.
The more subjective and unfalsifiable the criteria (e.g. chronic pain, depression) the easier it's going to be for looters to fake their way into the system. Even if it was possible, effectively gerrymandering the definition to include all and only those in need is going to be exceptionally difficult and expensive. A little bit of fraud is part of operating costs.
The problem we have with social media is that volume is the only thing that seems to count. Tribes don't generally police their own because the small hit to the overall credibility (which can be explained away as agent provocateurs) is a small price to pay for the additional 'voice'.
