From lion's linked article:
"And the needs of the Native American community are challenging because they look so different than the needs elsewhere, so they require a pretty significant coordinated effort."
This has always ALWAYS been true. It's been true since the mid-18th century when the first Peoples were pushed onto the first reservation in 1758.
The systematic dishonesty in treaty dealings, patterns of genocide, and neglect of basic human needs has decimated the Tribes. Not just the Navajo, there's not a Tribe or Band in the US that has not been impacted by this. CV-19 may have brought it to the public eye, but that's only because they've chosen to ignore it before.
