Technically standard american family does earn more than any other place on earth..At the same time standard American family also need to spend substantially more than any other place just to sustain life...
For example.....
Take energey consumpation per capits...
Because of the extreme weather in most of the USA, 90% of famiies need to spend money to heat homes...just to sustain life..same about clothes and footware....
For 80% of families in India heating cost for home is non existent...It does not denote lower standard of living....
Same holds for clothing and footwear...
I wonder how much of American GDP is generated by retailing and consumption of energy, clothing and footwear...??

Your source is ?
I have been in many places in the world, trust me, we have it the best in the US and by far :)
Comparing live in India to live in the US is just..... so difficult it is nearly not possible.
