Firstly, everyone knows there is no way for everybody to prosper in sync before society moves up one notch higher. Things happen in tandem. There will be people who will have to do catching up, and there will be those who will lose out in the race for prosperity anyway. The only people who believe that the world needs equity are communists. Again and again, it has been proven that human greed surpasses any attempt at equity and even equality. Four-legged creatures elected to replace their two-legged oppressors will eventually begin standing erect on their hind legs.

With the 'Clean India' campaign in full steam, open defecation is a thing of the past. With many states having 100% access to toilets, open defecation is a thing of the past.
Paradoxically, the country with the biggest economy must face the same problem. With its chiselled pavements and famous postcode 90120 that it sells to the world, even Los Angeles also has to deal with homelessness, drug addiction and cleaning up the sidewalks littered with human excrement.
Karma often plays its game most cruelly. The colonisers who robbed their colonies blind now have to be content seeing their descendants being fed by the descendants of their subjects. The innumerable hungry, homeless and impoverished British regularly frequent Sikh soup kitchens for a square meal.

Our experience from the 1960s space explorations has shown us there are many trickle-down benefits. Besides the numerous improvements in medicine and engineering, it also improves the life of the man on the street. Teflon was discovered. The knowledge to produce heat-resistant garments with adequate cooling technology becomes a game-changer in the day-to-day duties of firemen. Luggage bags with roller wheels have their origin in the space programme. At a time when the younger generation shows scant interest in STEM subjects, these types of ventures will surely rekindle their dwindling keenness. The Industrial Revolution and the subsequent leaps in civilisation did not happen because of economists and linguists but by scientists. Remember the economic opportunities that these ventures that offshoot from space travels. Money spent is not wasted but merely changes hands. Charity and social work can still go on.
The West cannot handle the paradigm shift in the world order. For more than two centuries, people of the Judeo-Christian traditions held the chalice of power. This century is when the power transfer happens from the West to the East.
