Feelings are important because without them, there would be a concrete number of dollars at which a person starves to death. One more dollar and they live. Once we know that number, the right wing will begin pushing everyone towards it.
Feelings are important because I want to enjoy a twinkie every now and then. I want to be able to afford a day off for mental health, or a friend's birthday. There should be healthy ambiguity in the number of dollars it costs to live because without it there's just near-starvation.
Anyone who claims they can hear the difference between an aux jack and USB-C is lying.
