It’s plain and simple concept of Purchasing power parity (ppp) . Spend some time digging through this concept .

It really comes down to how much of working hour an average income earner has to work to buy certain product or service . For example how many hours average earner has to work to buy 1000 sq ft house in US vs in Nepal , same with 32 inch TV or say some type of medical care.

Some product and service will be cheaper in nepal and some in US . But collectively US worker will have to spent lot less of their working hours to meet their basic need like paying for house , utilities and food . And they will be able spare remaining working hour to buy additional product and service like travel and vacation.

It also counts for things you receive from state for free like education, medical care where you don’t have to spent any working hours to pay for it.

If you do side by side comparison you will see clear difference between what average Nepalese worker has to spent to meet basic needs vs what US worker has to spent. It applies to everyone regardless of they are mediocre or not.

US is largest economy and richest county in the world . And everyone who lives here benefits from it. This is where power of state , it’s leadership and economy comes into play. Rich/extra smart/genius folks will live decent life every where in any country and conditions. How easy life is for average folks to meet their basic need , defines strength of power of state, society and democracy. Nepal is called poor country for a reason and average people in Nepal suffer because of that. On top of that nepalese society is poor on basic ethics and morals which leads to high corruption and bad leadership and continues to go in cycle.
