America is much better about this sort of thing. Aside from a few obvious holdover examples like the Pledge of Allegiance and the national anthem, the US doesn't bother with such ham-handed, last century techniques.
It's much easier to just coerce the media and get the public to consume the propaganda as entertainment.
And the native culture is thriving. All tribal languages are taught at school. No child is being sent to resident schools and getting sexually abused. The native population is has lower rates of suicide, substance abuse, obesity, poverty etc.
Sorry, I had to.
