According to wiki, the extent of aid to India, excluding military aid, is a little over 3.2 billion in US dollars this year. The current population is 1,270,272,105 people, half are under 25 yrs old. Seriously, 1 out of every 6 persons lives in India and there are more men than women. The aid is a drop in the bucket. The numbers are staggering for lack of education, the poor, infant mortality, and so on.
Some of the wealthy may be trying to make change and even there they run into resistance it seems. That doesn't mean a trickle down to the poorer populace. In fact, it is something to cling to because at least that is somewhere that they have control of the outcome. No one wants to have no control in their lives and it will be hard to convince folks of another way of doing things without widespread education and the ability to move upwards out of poverty.
