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.
