"Why don't the big email providers fix the spam problem?"
The spam filters on my email server reject 96.5% of all incoming emails. Probably about 5% of what does get through is spam. So assuming no false positives, that means 96.5% of all email is spam that is blocked, 0.2% is spam that is not blocked, and 3.3% is non-spam and that my spam filter correctly identifies 99.8% of all spam.
The big email providers do put a lot of effort into blocking spam, but getting from 99.8% to 100% is very hard. They can possibly manage more than 99.8% because they have millions of users clicking on their "report spam" buttons" which I don't have, but even so, you aren't going to get to 100%.
Your email box may be bad, but I don't think you appreciate just how much worse it would be if your email service was completely unfiltered.
