Two excellent reasons to OPPOSE gay marriage in the UK

I didn't assume you were talking about taxing income, but rather a sales tax sort of idea, what they call the Fair Tax over here in murica.

My apologies, but you did open with this:

...by requiring them to pay astronomically higher taxes relative to their income when they already bring in just a tiny fraction of what I have?

Bolding mine.

Yes, the percentages are equal numbers. Is the real-life impact of this equal? I've been poor enough where even a few dollars was the margin between eating and starving. I daresay this is never the case for a millionaire. A thousand dollars does not have equal relative value to me that it does to a millionaire. Ten percent does not have equal relative value to me that it does to a millionaire. It's a great idea in theory. In practice, it places the highest burden on those least able to bear it.

Given that the kind of systems I'm familiar with (UK and to a moderate extend, the US) have both an income tax and a form of sales tax, any real-life impact that currently exists would be much better for everyone if only a sales tax existed, because people would have more money to spend / save.

That is a great idea.

It's what we currently have in the UK. About the only good thing in the current system.
