^^regarding point no. 1,you indeed are a bit wrong though not entirely.the reason for getting domestic help is that if indian govt start hiring US citizens then spending bill will increase significantly & apparently indian govt is not so rich considering that ministers visits only for a few days but here we are talking about years(of course even a 2% decrease in corruption in FCI should be more than enough to cover this). as for wages it is more of a technicality as though indian housemaids get smaller cash in hand but they also get benefits like free accommodation,no worries about power,water bill etc which is quite a benefit in expensive major US cities like New York.
