Note, I am not here to make comparison, but you made some valid points. Before now, I always say this things that, someone who is born into wealth, as in someone who comes from a wealthy home will hardly make a good leader. But that doesn't mean that those Born into wealth can't become good leaders, they can if only they are ready to take responsibility, understand those from different backgrounds, and not to feel entitled. And according to how I see things from my perspective, I believe that those who are not born into wealth make good leaders than those born into wealth. Others users are still free to share their own 2 cent (opinions) on this matter.
Look norway it use to be poor country but they worked hard and now they are rich they have build also one of the secure sovering fund smart actions and good calculations.
Yes it seems poland is next successful nation because its not about inheritance and just ownership but also solving the real life problems and innovation.
We tend to live in short memory we tend to think world is only 30 years old thats the most timeline what people see in their adult life time but we should understood stagnasion and no innovation will halt all the old success and empires just ending up first to use all their old wealth and resources then they will even sell all what is valueble and then resources depleted culture gone power gone and national strengh weakened.
Leaders now understood this all but for many it might be too late.
Uk and many other failed on this a lot.
