There is a difference between a taxpayer and a citizen. Taxpayers includes people who are non-citizens, and even non-resident.

And some citizens are not taxpayers...

Neither term is sufficient with respect to the other.

Actually, in most of the countries of the World, less than 50% of the population are taxpayers.

Isn't that what I was saying? Just because someone does not (currently) they should not lose their rights as citizens.

Don't forget the sales tax. Pretty hard to avoid that.

True. But even if one were totally self-sufficient one would still be a citizen with the rights of a citizen.
