The IRS already openly admits to not auditing the rich as its too complicated and to instead going after the less wealthy.
This is a "viralization" of the article linked below, with this very clear headline:
The IRS Now Audits Poor Americans at About the Same Rate as the Top 1%

"The rich are not audited" is not an imprecise way of phrasing "The rich are audited at much as everyone else".
The IRS has identified that certain refundable credits (EITC) have a very high error rate (25-30%). As I understand it, it has created a mostly-automated mechanism to identify the filing errors that lead to these issues.
Should the IRS not be doing that because it lacks the resources to perform audits which are less subject to automation? Or should it not be doing that because EITC is only paid to lower-income households?
Some fraction of the incorrect EITC filings are undoubtedly fraudulent. What, in your view, is the acceptable rate of potential fraud that the IRS should detect, but ignore, based on income level?
