The “big five” banks in the states actually represent less than half the American population, whereas the major banks in Canada cover about 85% of us. (Note these numbers are from before the pandemic - I’m no longer involved in the banking industry.)
The US system is still incredibly fragmented, though a lot of consolidation is happening (yay oligopolies). Canada, on the other hand, has had stricter regulations for longer, which meant that even the 15% of Canadians with small banks and credit unions were included in the changes to the industry as they happened.
I don’t think that’s an aside, I think that’s the key to solving a lot of problems with our current society. Give everyone a roof and enough nutritious food, and most people can figure out how to live their lives from there. The problem is that the lack of housing and food options forces people into low paying jobs with no upward mobility, and continues the cycle of poverty.
