One thing I've noticed is that most of the discussion about colonialism in this country focuses on White land theft, and not much on the institution of slavery, despite the significant contribution of enslaved labor to the economic wealth of the country then and now, to generational wealth. The current prison-industrial complex (PIC) continues this by profiting from prison labor. The reason for this focus is that the initial and primary colonialism White Europeans brought to this land was settler colonialism.
