How and why the rich hold power and money

This is not breaking news, but I just had this penny drop! 

You know when I was finishing studies, we were in the middle of the millennium drought and I was finishing a degree in environmental and computer engineering so for my career it felt more meaningful and more relevant to go into environmental sciences. But nearly 20 years later, I wonder how much more money I would have made if I had gone into computers, since my research was specifically in the technology that forms the foundation of AI.

But look at the world around you, what we really need, is it AI or to tackle climate change? 

Been seeing Elon Musk, Jeff Bezos and the likes playing out in real time and realising that the rich find all the opportunities because they bribe and steal to be able to break laws or create laws or more likely have laws not be created where as the rest of us just want a fair deal, believe in the book and play by it.
