As they should be?

For a private company, QOL for someone doesn’t pay the researcher, laboratory chemical supplier, or lab’s landlord. Money does.

You won’t get a cure or treatment if you can’t discover it, get it approved, or distribute it, all of which costs (a lot) of money.

Inevitably, the bigger the quality of life improvement or more significant the impact = more money, so those measures are already indirectly considered.

It’s only incredibly rare diseases that aren’t receiving active research efforts.
