Yes, and that's why, even in brutal hypercapitalist America, we fucking regulate the free market.
And why we should abolish the free market in the long run, for that matter.
Because having the "freedom" to buy poisonous adulterated foodstuffs, if you're too poor to buy real good food, is like having the "freedom" to accept sub-minimum wages if you're desperate enough for money. Not freedom, but exploitation.
