The working poor do in fact have social security and Medicare payroll taxes deducted from the very first dollar of their earnings currently and that IS very regressive.
The founders did in fact favor taxes on articles of consumption as their favored method of taxation. There are MANY proofs of this fact and I will offer two here.
"It is a signal advantage of taxes on articles of consumption that they contain in their own nature a security against excess. They prescribe their own limit, which cannot be exceeded without defeating the end proposed - that is, an extension of the revenue. When applied to this object, the saying is as just as it is witty that, "in political arithmetic, two and two do not always make four." If duties are too high, they lessen the consumption; the collection is eluded; and the product to the treasury is not so great as when they are confined within proper and moderate bounds. This forms a complete barrier against any material oppression of the citizens by taxes of this class, and is itself a natural limitation of the power of imposing them."
From Federalist #21
"A capitation is more natural to slavery; a duty on merchandise is more natural to liberty, by reason it has not so direct a relation to the person."
Thomas Jefferson's Commonplace Book.
The income tax did in fact come to us straight out of the Manifesto of the Communist Party second section, toward the end, item #2.
