"Everyone can cheat" is not making the poor equal to the rich, not at all. The rich gets 2 things: they can pay for stuffs and they can get away for stuffs just because they are rich. The fact that no one is paying does not mean that magically the poor can get away for stuffs.

The things they can get away with includes, for example, the fact that they don't get fired when they don't know their job. The poor still gets fired, the fact that they can now cheat more easily just mean they are shooting themselves in the foot.

The rich and connected adjacent to accounting and willing to cheat would have most probably already worked somewhere else money-related and making an order of magnitude more money.
