[quote=CardiffBaseball]I would like to know how a flat tax is regressive? Most proposals exclude a certain amount of income automatically making it progressive.
Let’s say we had a 20% tax on all income over 50K.

In which case, you have a regressive tax on all income over $50,000, because a greater burden, relative to resources, is placed on those with incomes, say between $50,000 and $150,000 than those with income over $250,000, since basic needs are still being met at marginal income above $50,000, but not above $250,000.
It would be less regressive than say a VAT, but regressive, nonetheless.
