NO!! i don't buy into that people are inherently evil, But selfish oh yeah! which could be considered the same thing in a lot of situations. If people wer'e inherently evil the world would have ceased to exist long long ago.
But selfishness sadly makes up for many things gone wrong in this world and people get's too often consumed in their own greed and completely loose focus (Studies show that when you gain power and control over others you're way more likely to develop narcissistic traits).
There's actually nothing wrong with capitalism in general as it provides wealth and "can" fund the wealthfare of the people, Problem is when it starts to turn to greed which often (Sadly) happens when it's unregulated and given free access to develope on it's own.
Take Amazon's owner Jeff bezos as an example, This guy is so rich that you can't even in your wildest dreams imagine how much money he has, And still his employees works for slave-wages that would make any Danish union run away screaming (This is a perfect example of selfishness or greed if you like) The American tax system even benefits people like him.
We need to invent pills to remove selfishness in all humans, I wonder how the world would be then
Oh joy!! people will be singing and dancing and as soon as you open your front door you'll be attacked by horny blond women, And having "sex" less than 10 times a day would be considered a serious crime (Damn it was only dream)
