Consolidation matters when private power becomes useful to government and costly to the public.
This archive is not a general business history. Each acquisition is being organized around two campaign questions: how the consolidated entity can help government or public institutions, and what allegations, documented harms, or constitutional-adjacent conflicts later affected citizens, workers, customers, creators, patients, tenants, farmers, or communities.

Accumulation view
Consolidation is additive; it does not reset each year.
Annual M&A counts can understate the public-power problem because completed deals remain part of the consolidated economy. This view adds each year of global M&A activity and compares that accumulating stock to business-formation activity and wage growth.
