Someone can check my numbers but I believe the discretionary budget for the USFS and BLM in 2024 is something like 10.82 billion dollars combined. The BLM brought in over 7 billion in revenue. Not sure what USFS revenue is.
So, assuming population of ~340 million, each American paid roughly 31 bucks to manage and have access to hundreds of millions of acres of BLM and USFS land.
I don’t mean to come across as pedantic, but your math assumes that every one of the 340 million people in the country pay the same amount of taxes. They do not, and close to half don’t really pay much of anything towards things like this.
