Final answer:
People who are uninsured often do not have health insurance because their jobs do not provide it, which contributes to rising healthcare costs in the United States.
Step-by-step explanation:
People who are uninsured often do not have health insurance because their jobs do not provide it. This can be due to their employment being temporary or part-time, or their employers simply not offering health insurance.
As a result, many uninsured individuals have to rely on emergency rooms for healthcare, which is the most expensive form of healthcare. This contributes significantly to rising healthcare costs in the United States. For example, prior to the Affordable Care Act (ACA), more than 32 million Americans were uninsured.
