VAT provides an incentive for businesses to register and keep invoices, because they automatically pay more for tax they can't show invoice.
I just found out that many people in the US have opinions against it when Trump/Vance did bring out VAT into the discussion, so I felt I had to confirm my assumption that VAT is nearly universal. In some ways the US attitude is like UK was in the 1900s when it comes to infrastructure of governance "old things work just fine."
