Authors:
John Geyman

Int J Health Serv 2021 May 14:207314211015806. Epub 2021 May 14.

12353University of Washington School of Medicine, Friday Harbor, Seattle, WA, USA.

Investor ownership of US health care has grown exponentially in the past 50 years through ever closer ties with Wall Street corporate interests. More recently, private equity firms have accelerated this process, invariably with harmful impacts on access to affordable care, its quality, and profiteering, with little accountability. These impacts are fueled by several concurrent trends: (1) increasing privatization, (2) consolidation and mergers, (3) increasing bureaucracy and waste, and (4) profiteering that may bleed into outright fraud.
