The Sky Train

Since my connecting flight to India was departing from a different terminal than the one in which I landed, I had to take the Singapore airport monorail to get there. After the next train approached, I stepped into the packed car only to realize that every single person in it was Indian. After I descended, I started noticing how the majority of the people in the airport were Indian, as a matter of fact. Has the combination of the Chinese one child policy and Indian policy of well, doing nothing to curb population growth skewing the global ethnic ratio? Are we slowly taking over the world through sheer number?
