It does seem that way sometimes doesn't it?
If the world seems like it is trapped in one big negative feedback loop then there is only one way to brake it.
Be positive. Be kind. Smile. Give. Give more. Don't stop.

This will pay off big for you. You will be a happier person
and those who do treat others the way they want to be treated
will want to spend their time with you.

Let the mean and grumpy folks enjoy the company of their own
kind.
don't worry, be happy.
