You really don't benefit from it at all if you're under 80th percentile for income. taxfoundation.org/salt-cap-r…

Literally no other country in the world has this sort of tax exemption. Our tax code is built on the idea of progressive taxation. If you're at 80th percentile for income, you are paying for everyone below you, SALT or no SALT. Why give tax breaks to the rich?

If this isn't a tax break for the rich I really don't know what is, man
