Yes. But, I was addressing what you said about Americans paying taxes. But, churches are also exempt from paying property taxes. Quick Google search found this:
"Are churches exempt from having to pay taxes? The short answer is "yes." For purposes of U.S. tax law, churches are considered to be public charities, also known as Section 501(c)(3) organizations. As such, they are generally exempt from federal, state, and local income and property taxes."
Again, any church that is genuinely acting as a charity, would still get their tax exemptions. The con artists, getting rich off their parishioners, would get exposed. All for that!
