Most adults are mentally well adjusted enough that the mental scars of early torture by long-division fade into the background. Even adults that dislike math need to use it in their day to day lives. I don't think the math that many people truly dislike because of its perceived uselessness, like geometry and algebra, need to be mandatory, but someone with a McJob needs to make change and calculate their monthly wage from their hourly wage.
I would be curious to hear your examples of someone leading a successful life while irrationally avoiding all math.
People with a McJob don't need to calculate change: that's the cash register software's job. And many people avoid calculating their wage or budget -- their spouse does that kind of thing.
Perhaps you will reply they at least need to be able to count to 4 to hand back the right number of each coin. And need to be able to read numbers to answer questions like, "What does the Super Mushroom Burger cost?"
But the blatant usefulness of a skill is no argument in favor of required education of it -- won't people want to learn it voluntarily? And those who disagree, why can't you leave them alone?
