Algebra is useful for all kinds of things to help one excel in life. For example, even to do one's own taxes, the IRS worksheets involved require using a little algebra. Very useful in many aspects of managing finances.The main purpose for algebra is to identify students who will go on to courses and/or careers that require advanced math. Probably less than 1 in 1000 students. It is good to stretch your mind, however. My teacher told us that if we remember nothing else to remember how to calculate ratios. He was right.
Interestingly, you don't start needing algebra for managing finances until you have significant money. Wonder if there is a reverse correlation there - if you want to be rich, chances are it might help to know algebra.
Knowing ratios is good, like you said, helps to figure out which choices at the supermarket are better deals (although many supermarkets do the math for you now, and show price per ounce or whatever).
I'd guess that in addition to technical professions like engineering, lots of skilled trade professionals use algebra, and it's probably essential for many who run successful businesses.
