Poor people pay a higher share of their income than rich people.
Ah, yes that is 100% true and likely to be true of any VAT implementation that hits consumer goods. If a VAT could hit B2B transactions only, it could be possible to "tax the tech companies"
The beauty of a VAT is that there is nobody determining the difference between consumers and business, it's just transactions all the way down, with later ones verifying the earlier ones.
