"Do you trust the IRS to say, "It's okay if we lose $5000 - you're happy, right? That's what matters!"? Of course not. Having the separation works in the US for this clear conflict of interest."
I really think you misunderstand the intent and mentality of the IRS. You seem to be projecting a capitalist objective to their actions with the motive of obtaining the maximum amount of money. The IRS does not have any direct incentives for bringing in more money.
If you are audited and the auditor finds you missed deductions, they will tell you. I would hope that information should be enough force a change in your perspective.
