In the 90s, I knew someone whos parents owned something like 300 acres of land. It was farm land that they leased out to farmers....the made a decent income from rental but definitely only like middle-class income.

Their parents died and so was left to him. The "exemption" was something like 500K....and the 300 acres were probably valued at $1.5M....so he was hit with a tax bill on the $1M.

Obviously this forced him to sell off the land. Its how the gov destroys familial wealth.

Thankfully I think the exclusion is much higher now.
