Unpopular opinion : You can only blame colonizers for so much.

The same can be said for Joe Six Pack in his red MAGA hat who wails about immigrants taking their jobs and others being on welfare as he collects his unemployment checks; rather than acknowledging his high school education or less and lack of better skills have failed to equip him for an ever evolving and changing workplace. Certainly his cultural upbringing to believe that a simple rural, small town, basic job in a technology-free workplace was good enough for his father, grandfather, and great grandfather has influenced his inability to evolve as well, but it still comes down to his individual choices not to seek more education, training, or re-training. As you say, you can only blame colonizers or cultural backgrounds for so much, but then you cannot totally eliminate it either.
