You compared the effects on "millions" of global poor vs. "millions" of poor americans, but there are order of magnitudes difference in the size of those groups. Arguably the gains to the former is also greater than the losses (the rural poor of south and east Asia gained food security, the stakes are not nearly that high for the American poor).
