Minimum wage is, sure, not the cause of deindustrialization. Rather, it's what people tend to advocate as a cure for a large underclass stuck in poverty, but it's not addressing the core issue. We have a larger underclass stuck in poverty, because the kinds of jobs that historically allowed them a way out of it were sent to places with even poorer people, and the change that allowed that was a change in government policy (tariffs, etc.). So a minimum wage, like a blood transfusion, might help out for a bit, but it's not addressing the underlying issue, which was a (major, sustained) change in government policy.
