I'll take you off ignore since at least you'r asking questions.
You started this by claiming that income taxes are visible and that you know your income taxes exactly.
First ask yourself, do you really think anyone else here doesn't know their personal payroll tax? Of course they do! So ask yourself why are they saying income taxes are hidden? It's because they are referring to PRODUCTS! They are not referring to your paystub.
Your response should have been, "Okay, now I see what you meant by invisible and I agree that income taxes, as part of the price of a product, are not visible. But how do we know taxes form the bulk of a product's price?"
By responding in that way you would have appropriately engaged an informative discussion on this topic. Instead you have launched into your own polemic.
I hoped I have reached you and that you will be a better person for it.
