The point, at least as I interpreted it, was that society is very good at building callous machines that throw away human lives for no reason and then the same society turns and pats itself on the back for the incredible virtue it has in allowing those people to "heroically" destroy themselves.
These countertops might not even outlive the people they're killing at a young age. In the past 15 years, I've talked to people who have gone from needing granite counter tops, to quartz, to the next trendy fashion. If a countertop killed me, then I would hope that it would last a century, but the truth is that it might not last a decade simply due to being unfashionable. And somehow I doubt its replacement is going to be any safer to cut.
