>Many western countries have very simple or near-automatic tax systems and I would argue that the tax you pay is actually much more visible to residents of such countries.

I think if you want to counter the poster, you need to give an example of a western country that has simple/automatic tax systems and have a lower tax rate than the US.

His/her complaint is primarily that if a system is too simple, it's much easier to raise taxes. You're giving exactly the example he/she is looking for - a country where it's easy and the tax is higher.
