Of course the racism in these ads is deplorable. But I think if you're going to study old advertising, you have to look at the ugly stuff, too. To ignore its existence would be to ignore the pain it caused.
It certainly looks as though Union Carbide has cast itself as the hand of God coming to rescue India. If that message doesn't offend you, read this excerpt from Pollenatrix:
In 1984 Union Carbide's pesticide plant was responsible for the worst industrial accident in history. Union Carbide had frequently exported "untested technology" to the Indian plant, which was poorly run. It had imposed a huge cost-cutting program at the plant, causing safety measures to be scaled down (they were all malfunctioning or turned off at the time of the accident). No disaster planning was in place. The disaster immediately killed 3,000 people, and 15,000 more died later from injuries. The estimated number of people injured range from 150,000 to 600,000; 20 years later, people are dying from contamination in soil and water that has still not been cleaned up.
