"If it moves tax it. If it keeps moving regulate it. And if it stops moving subsidize it" --Ronald Reagan (b. 1911)
That is, driven by this statement, prostitution and cannabis would have been legalized in the US long ago - after all, why make something illegal if you can instead tax it?
(This is my understanding of how Switzerland, where cash is king, does it).
That aligns more with my understanding of Reagan's economic ideas.
