I was under the impression that VAT taxes are considered to impact mostly the poor. While in absolute terms the rich are impacted most, in percentage terms VAT is considered a much smaller portion of expenses for the rich than the poor. I quote:
"VAT is a regressive tax, putting more burden to the poor than to the rich. Indeed, VAT applies the same rate to everyone regardless of their level of wealth – but the richer you are, the lower the proportion of your revenue goes to consumption."
In the U.K. most living expenses are don’t get charged vat, or get charged at a low rate - food, rent, public transport are vat free, electric, gas are low rated.
