alt Hacker NewsStumpy Nubs over on YT gave some testimony where he believes that a well-made blade guard could prevent most injuries. He believes that it's a culture around not using them (or poorly-made ones) that is the source of most injuries.

The blade guards on the cheap tablesaws are awful and everyone removes them. The good table saws come with guards that work much better (but still not perfect sometimes you have to remove them but most of the time they work well). You can buy a new table saw for under $100, a good blade guard can be bought separately for $300 so you see why a lot of saws have cheap guards. (note that the cheap tablesaw too light duty to support the good guard)
Every tradesman knows people that actively refuse to use PPE and other safety equipment. There's are huge social stigmas against it in most crews.
