A stronger central government was good news for Native American tribes.

Answer 1

There was a massive genocide of Native Americans by the colonial governments of the US, Britain and Spain. 12 million Indigenous people died in what is today the coterminous United States between 1492 and 1900. Between the gold rush in California, forced relocation of the trail of tears in Oklahoma, Andrew Jackson's policy of exterminating natives, there is absolutely very little which could be said of how US federal government has been "good news" for natives. With exterminating somewhere close to 80-90% of the original peoples of this land and those who survived putting them into essentially concentration camps and destroying their natural ways of living, the US government was only a threat and bully to native populations. If you'd like to research more about this, you can look at Howard Zinn's History of the People. You can also watch 500 Nations, or research how most of the buffalo and food sources were killed by federal government.
