Congress hasn’t been able to pass an amendment since the 90s, and even that was mostly theater regarding their own compensation proposed in the 1700s. The last real amendment was passed in 1971 lowering the voting age to 18. It’s been almost 60 years. Most Americans don’t know what a functional federal legislature within their own country even looks like.
