Debt issuance does not create growth. It reallocates purchasing power forward in time.
Real growth comes from productivity gains, better coordination of capital, labour, and technology. Under sound money, growth shows up as falling prices and rising real purchasing power.
Construction sites are not proof of growth. Malinvestment builds things too, until the cash flows fail and the debt must be rolled, inflated away, or defaulted on.
Issuance expands claims, not resources. Eventually the claims exceed what the real economy can support. That is the bottleneck you’re describing, and it’s caused by debt, not fixed supply.
