There are sham "training centers" all over key cities in India. The degrees and fake certs are rampant, as you stated. As you allude, they're very "tribal" once an indian gets into the position of power and hiring, they will get rid of any one who is not indian. Dealt with this guys for years, both in the states and in india itself. Indians cannot think outside of the script / box. It's a cultural thing from the days of call centers and such. They have tried to get independent though and skills out of the native born, but it's real tough.
