Question to all designers

i have a doubt
that cames to me speaking with a friend who is also a designer

what designers do for people? for humanity?
ok, we make something look preety, but does everything has to be pritty? looks nice?
if the things arent nice in society, why do we make it visually nice?
many works are directed to society, people, and things that help to our progress. but does design do those things?
i really want to know who else has these question and if someone can find a answer

greetings
