Realistically, if you have a large sum (millions) you can invest in safe blue chip stocks for steady dividend and long term ROI but if you're looking for short term gains, I would highly recommend you invest your money into your own business or education.

This is a scenario that rarely happens outside of fiction. Even though the common folk have always had numbers on their side, it's almost never utilized.

That would work for someone having an off day. Not an actual shitty person. If they knowingly didn't reply for half a year and only messages back when they wanted to use them, that's likely an actual shitty person.

Shitty people usually lack empathy, which is why they are ok with being shitty. If you treat them with kindness, they are much more likely to keep abusing the situation. When I refer to a shitty person, I'm talking about narcissistic, machevellian, slightly sociopathic types of people.

I find that treating shitty people kindly just lets them know they can continue being shitty and people will still be nice to them. Accidents happen and people deserve some leeway but if someone is known for being shitty I think it's better to give them the same energy they put out.

I'm honestly surprised

Because somehow enough people were convinced anything that wasn't democracy was communism but also that capitalist fascism is actually democracy
