True, but that does not make it morally right and it certainly does not make it right to impose further burden on these people.
Collecting taxes is also puts these people in legal jeopardy.
What many people do not realize, is the tax collecting burden on retailers and service providers is already very onerous. Not only do taxes vary at the state level, but various cities and counties also have different and special taxes. You’ll notice my post did say the fact that they already collected taxes was not a reason for them to collect more.
