The United States is fantastic in many ways. It's a diverse country full of people from all cultures and backgrounds, and people come from all over the world to visit it. However. one thing that IS wrong with the United States, is its healthcare system.
Most other industrialized countries in the world have a single-payer healthcare system, otherwise known as universal healthcare. In these systems, people typically pay high taxes, but those taxes go towards funding healthcare for every person in that country. When someone in a universal healthcare system goes to the hospital, gives birth, requires chemotherapy, or anything else - they don't pay for it. It's paid for by their taxes. If they do pay, it's very minimal.
In the United States, healthcare is a commercial business. It's not geared towards helping people- it's geared towards making a profit. We pay taxes that go towards funding Medicaid and Medicare, but a good majority of people in the US don't qualify for those programs. On top of paying these taxes, we pay insanely higher premiums for health insurance, and then on top of THAT, we pay fees for the actual medical care- fees that our insurance wouldn't pay.
Basically, healthcare is a privilege in the United States, when it should be right. Take a look at these sentiments on the topic.
