I don't think any political model is "perfect", whether it be capitalism, socialism, communism, republic, monarchy, aristocratic, oligarchic, caliphate, sultanate, plutocratic, theocracy, etc.
Each have their pros and cons, and some systems work better than others, but like I have said, nothing is perfect or flawless.
More often then not, those in the politics and business, have the greatest potential for corruption, where they will exploit the system for their own gains.
I find it mildly amusing that you would defend capitalism against the science of climate change.
- Capitalism isn't science.
- And climate change isn't politics or economics.
And furthermore, climate change isn't a religion.
That you would even consider climate change to be religion and socialism, just showed that you are desperate enough to use flawed reasoning.
