I think it is because of population vs resources allocated per person. When a nation is developing it is still trying to catch up with the high number of population it can service, but with little resource it can utilize or there is but not yet utilize. It has no choice but to cut corners in turn lower standard of education, health, social services, housing and unutilize laws. This in turn having some or majority of the people receiving less and some none at all. This makes them vulnerable to bad influence and bad decision e.g. vote buying, rebellion. They cannot participate in the nation building process in a right mind since they are trying to survive. Anyways, I'm probably just talking bullshit. To be fair not all Western nations have high standard of living e.g. some nations in eastern Europe.
That's because it's in the east, we're talking 'western' here mate.
Jokes aside, citizens in developing nations are struggling with food, basic necessity and shelter while western people are generally not concerned about a roof above their head making them worry about higher level needs like education, Healthcare and improving their quality of life.
For example, a large population in India are seemingly 'wasting' their life unproductively while in reality they don't even have the right psychological mindset to improve their conditions. And if, or when they try, it's pretty easy to hit the brick wall of a meaningless rat race without any end in sight.
Easy way out? Scam people, sell drugs, local politics and other harmful activities that would give any kind of recognition (which again, is a basic need)
