My days in UK i could say was good so other countries should check uk specially the USA and canada no homeless on the streets i guess people live really well in UK i got very good impressions.
I am afraid you are a bit confused about the roles in the UK. The king and queen have not "created the country", they are mostly rich people who benefit from the country and are mostly ceremonial.
The UK and many European monarchies have been left in there for simbolic reasons and it has been the people that have created a country that works and has law. That could also be done in your country if people were seeking peace and working together, but that is not easy.
