Yes, and cigarettes, asbestos, lead in gasoline, and a few others, too. Clearly there is a place for education and coordinated action among the common people.
It's one of those "if we put a man on the moon, why can't we solve this damn thing" kind of problems.
Throughout my life I've had various girlfriends complain about poorly-fitting bras, especially ones with under-wires that bite or break. It really seems like it should be a solved problem, but I kinda don't think it is.
Speaking of mixed units, don't forget the alwys fun distinction of avoirdupois pound vs troy pound...
People sometimes ask "what's heavier, a pound of feathers or a pound of gold?", the implication is that you're stupid for for asking a dumb question. The technically correct answer is that the pound of feathers is heavier. The expected answer is usually that they're the same weight, because there is no difference in weight between the two things that both weigh a pound. The problem is that, in the USA, a pound of feathers is measured with the avoirdupois pound, while a pound of gold is measured in troy pounds. The troy pound is lighter than the avoirdupois pound, so the answer is that a pound of feathers is heavier.
While a troy ounce is heavier than the avoirdupois ounce, and the grain unit is equal in both. So, depending on whether you ask for a pound/ounce/grain, the answer can change. https://en.wikipedia.org/wiki/Troy_weight

Give the guy some credit... No, clearly CGMthrowaway is not assuming that at all, it's purposly left out. The first sentence mentions "back of the envelope math" and makes it clear it's a rough order-of-magnitude estimate. Also it's in response to a statement about "wondering how you could get such a high impact overall". Also, also, the last sentence is "So it tracks, roughly. And we are not at the bottom yet."
It's perfectly fine for people to do rough estimates to understand a situation, especially in informal discussions. It not a dissertation for a Ph.D. or formal position paper.
