Can GDP grow on investment alone while household incomes weaken?
Core argument: Data center construction employs workers in the thousands during the build phase, only to fall to a hundred or fewer once the facility opens, illustrating that capex generates capital formation and corporate revenue rather than wages.
GDP can rise with investment ("I" in GDP terms), despite everything else in GDP being weak, or even falling. It is just math. Capex does not necessarily generate broad income growth. It generates capital formation and corporate revenue, not wages. You can see that directly in data centers, where construction jobs are in the thousands, only to collapse to a hundred or fewer post-opening. The result is a strange possibility: the economy can grow rapidly, at least in accounting terms, while the demand side weakens badly. That is the essence of Ghost GDP. One place this dynamic would show up quickly is household credit. Mortgage obligations are nonlinear with respect to income changes. Debt service is fixed in nominal terms, so even modest income declines can push borrowers toward default. Once debt-service coverage ratios approach one, default probabilities rise sharply.
