Am I Too Simple-Minded?

   Maybe I'm stupid, but it seems to me that if more people were employed (thus increasing revenue from income taxes without raising the rates), then more people would buy stuff (thus increasing revenues from sales taxes, excise taxes, property taxes, etc.).  And if more people bought stuff, there would be an increase in demand for stuff, which would result in hiring more people to make stuff and to transport stuff and to sell the stuff.

   Sounds almost too simple.
