Salt dietary guidelines: Why do food manufacturers use so much salt?

I'd take any such guideline with a grain of salt :)
So I started paying attention. I was amazed at how easily you could fly way past 2300mg while still eating healthy otherwise. I began reducing my sodium intake on purpose, choosing low-salt or no-salt options when available, and cooking with less or no salt. (It's not always easy to find low-salt packaged foods! Some things I just stopped eating altogether, or eat very little of.)
It was initially an exercise in blandness, but now I'm quite used to the flavor, and am disgusted at the idea of eating as much salt as I did 2+ years ago.
I don't think there's any evidence that we should be curtailing our consumption of salt anymore (although I'd be interested in the details if there were still reasons), but the main reason for me to curtail salt intake is because eating too much salt lowers my ability to taste salt, and salt is good.
