Spain's corporate elite is dominated by interconnected networks of executives who share backgrounds at elite consulting firms like McKinsey, prestigious business schools such as IESE and ICADE, and government institutions. McKinsey alumni hold key positions across Spain's largest companies in finance, technology, and media, creating an influential web where consultants often transition to client companies. These networks extend to civil engineers trained in Madrid who have founded major infrastructure companies, illustrating how educational pedigree and professional circles concentrate power within Spain's business establishment.
