Why people are so stupid?

The thing is ... I live in a small coutry on an island. Where i live most of the people know each other. I know lots of people and i got this single question (i am a male to begin with) why are people so stupid? by that i mean, why don't they think?

Facts:

- When you say to someone: Hey, i know where this is going, staph.. he will just do it.

- The only way a person can be in your place, is ONLY if you ask him to.. he won't even try alone.

- People.. most of them... feel lonley... and a big number of them knows that social media (and especialy those whitch you can take with you) are the biggest reason for that.. why don't the just stop using them? or at least try to suppress it's use!

- every single and one of us really tries hard.... for his image only.

- No person EVER can feel what you feel... so why do people always try to confort you, even if both sides know that the "it's ok dude, you'll get over it" or the "i feel you" is a BIG lie ..

- The biggest thing in this question is that people are stupid cause they don't want to think themselfs... they always relly on others... that is stupid but why people do this?

i have more but right now i am really dissapointed on the humanity .. i am tired in solving everyones problems (mine too ofc) and all the problems that i have, even if it concludes others too, again i am the one that tries at the end .. why can't people be nice, just, equal, reasonable and above all... WHY CAN'T THEY JUST GET THEIR BRAINS THINK? .. it's lame ..
