(Quick aside, just wanted to mention that I hate how this post has -15 votes on it. Its a relevant question to at least discuss, at this time in history.)

To answer the OP, because its the right thing to do, if you care about others, and care about how others would treat you. A.k.a., “The Golden Rule” (the Socialist one, not the Capitalistic one).

If you need a more “closer to home” personal/selfish type of answer, I’d say because if everybody, and I mean EVERYBODY, plays the humanity system to their benefit over all others, then the center does not hold, and humanity collapses. And our lives and/or happiness then is at risk during times of anarchy.

Try to remember that, as a species, we’re very young, still evolving, from the animalistic (“Every person for Themself”) to the spiritual (“One for All, All for One”). Things swing back-and-forth, over time. Can’t have the Good without the Bad.

Also, cooperation is bred into us, at the meta/species level, less so at the individual level, but still somewhat there too. It can be trained/psyop’d out of us during childhood, but its there. But overall, we’re each other superpower, in a tame sort of way. Imagine any problem, then imagine what it would be like if everybody worked together to solve that problem. That problem would be solved.

When you see everybody else around you cheating and winning, and getting ahead of you, its tempting to do the same. But if you’re not that kind of person, you lose a part of yourself if you acquiesce to those negative feelings. Its better to be able to look in the mirror each day, and like what you see looking back at you.

And finally, remember, there are others that believe the same way you do, even during the darkest times.

Edit: Typos.
