Better outcomes in health, education, and overall standard of living are the reasons “settler” culture swamped Indigenous cultures. It wasn’t plotted in a colonial back room. People adopted lifestyles that were healthier, less physically strenuous, and more stimulating, and that process never stopped. The “dominant” culture today is very international. To pretend that this process would’ve been reversed if it wasn’t for some “bad” colonialists is a false narrative. Indigenous have freely chosen much of what’s on offer, but that doesn’t distinguish between the individuals within each cultural group who have made a variety of choices for different reasons, many of which have little to do with settler/Indigenous culture but result from universal human traits like talent, motivation, education, upbringing, etc. All living things avoid pain and seek pleasure. There are good things about Indigenous cultures, and many such qualities have been adopted by settlers. That’s what humans do, incorporate successful adaptation strategies.
