But that's the same as saying ignorance is a bliss.

You might have problems but you haven't thought about them, or in some case you can't even verbalize them.

Other times problems just become background noise, and they're there in plain sight but you're used to them - and they can have negative impact on your life.

We're not machines, problems aren't binary.

Now if you say that we as a society, sometimes, value the "wrong things" (which is subjective) and see problems that aren't a big deal, it's true. But you can't pin that on advertising - those are symptoms of poor education systems, poor health, and I'd go as far as poor value systems.

Well a problem could be averted before you have it. There are lots of examples: Like buying a kinesis keyboard before you actually get RSI. Or an ergonomic chair. You were heading towards a problem, but might not know without an “ad”.
