Another inequity: corporations can deduct their SALT, but individuals can only deduct $10k of SALT. So many people derided
Citizens United (corporate campaign contributions case) as granting personhood to corporations. But the new tax law actually grants
more rights to corporations than to people!
Of course, I understand that corporations have always been able to do lots of things that people couldn't do, such as enjoy limited liability. But these are very close analogs, and there aren't any compelling policy reasons as to why corporations should get unlimited SALT deductions if people aren't given this privilege.
