Calcutta slums versus US slums.
Is India perfect? Far from it BUT, consider how the average Indian's life has changed versus the average American's (and Canadian's life) in the past 40 years. Consider the explosive growth in Christianity over that period. Officially, it is 2.3% but, including house churches, it is estimated at 6%, or 60 million and growing! in Canada and the US, it has imploded, not exploded! THAT is a spiritual explanation why the West (The US,Canada, Western Europe, Australia, etc.) is failing and the South is surging financially. (India, China, SE Asia, etc.)
