• Insurance companies scamming people out of support while their profits skyrocket year after year

• Insurance being tied to jobs, but only some jobs that aren't tailored around denying worker support

• Insane hospital markups, price gouging

• Pharmaceutical companies, also with obscene profits, squeezing as much as they can out of vulnerable people.

• Lack of Government assistance or intervention against those issues, expansion of medicaid in a lot of areas, or a public option. Anything resembling what other industrialized countries have.
