Are you asking how much it would cost a middle class family to live in the US for a month?
It varies wildly between parts of the US, and the rural vs urban areas. In Boston Massachusetts, for example, the median family of 5 makes about $6,000 after taxes ($84,195/year before taxes). In poorer areas/states, like Mississippi, families of 5 live on average, with $3,700/month after taxes.
Food, clothing, housing is 10x cheaper in india at non luxury quality. Internet, electricity, gasoline is more expensive than the west. A few things like corruption free living are just not available though. Hopefully this will change after changes like this. I am very optimistic.
