There is probably an easier conclusion and that is the cost/benefit analysis of chasing illegal money. Firstly, a lot of what is happening is legal or at least a grey-area. Secondly with the complexities of multi-juristiction money and 100s of layers of obscurity that a rich person can afford to put between them and their money (legally), would you bother spending 100s of 1000s of dollars looking into it after which you might not find anything that can be prosecuted? It costs little to look at a much simpler Joe-Blue-Collar worker. Sad but true. The only way I can imagine it being resolved is by requiring full traceability for all financial transactions so I can literally tell where all the money in an account originated from. Can't see that happening.
