  • Get Government Revenue estimates from the changes, and balance them against savings.

Disclaimer

I'm not qualified in anything related to this stuff. Actually it's worse, I'm a computer programmer and we're supposed to be better than spreadsheets.

UBI are a way bigger change for this model to take into account of all the effects. It's really just there to give an idea how it would be affordable.

If you know stats or economics or whatever, feel free to tell me what I've done wrong.

Pull requests welcome.
