Wouldn't the world be a much better place if we all stopped being so individualistic?

Why can't it be like back in the days where people were fighting together like brothers for noble causes and treated each other as brothers and made jokes and all, it had more validity and a good story behind it...Now it seems like it turned so cold, boring, stupid and empty. (being born -- go to school -- go to work -- die)... at least you had real trolls back then LOL jk (not the wanna-be intellectual trolls you have now) Although there were many diseases back in the day and all that bad stuff but that doesn't really matter for me, the pro's outweigh the con's in my opinion..Who agrees with me?
