That 70% figure for Indians is likely due to resume fraud. The east and southeast Asian countries listed have much better educational systems than India.
I wouldn't call it fraud, but India does have different standards for a college degree. I've seen cases where their college degree was more like a vocational or trade school degree. The US would at best consider them to be associates degrees. It's complicated by the fact that many Indian degrees are from institutions equivalent to a college engineering degree. Without inspecting the actual transcript and knowing the texts used, it's nearly impossible for an American to tell.
Guys, remember that immigrant communities are NEVER representative of the countries from which they originate. Most Indians who can get a visa to the U.S. come from the upper classes/castes, and are thus by far the most likely to know English, hold degrees or be well-educated. They are here because they have had access to opportunities of which the typical Indian cannot even dream. Only at tiny, tiny fraction of the overall Indian population is here: even if there are a million or more people of Indian origin in the U.S., there are hundreds of millions more in India.
