Which is why schools are supposed to teach people this stuff. Indeed,
schools teach a whole bunch of stuff like woodwork, chemistry, and a
bunch of other things that only a tiny handful of people will ever use.
I think you could successfully argue that even if nobody in the class
ever needs to use algebra for anything, learning to do algebra teaches
you logical thinking, which is probably quite relevant to daily life.

Remember that I went to a school for mentally retarded people. They
didn't even teach us what a square root *is*, never mind how to compute
one. (For that matter, they didn't teach us what a square is in the
first place - other than that it's like a rectangle, but with equal
sides.) The only "mathematics" we did was filling out page after page
after page of long division problems. Because, after all, mathematics is
all *about* long division, right?

Heh, point taken...
