I could not make it through the whole article: Too long, too slow, for me. However, I did read about half of the article.
My thoughts: It's tough to take a completely different culture and try to compartmentalize it within the morals and beliefs we, as native born US Citizens have. Yes, Lola was a slave, for the most part. Yes, the author's parents were pigs, and phonies, as the same applied to their treatment of Lola.
Thing is, this practice involving Lola, is commonplace in the Philippines, apparently. While that doesn't excuse its horrendous existence, it does explain everyone's behavior under the system.
I feel sorry for Lola, but I wonder how more horrible her life might have been had she stayed in her village in the Philippines.
