As the nation gears up for the 2020 election, Democrats are promising bold new changes to the American health care system. One idea championed by many on the progressive left is “Medicare for All,” or a single-payer system, which would do away with private health insurance for most forms of care. Advocates of this plan promise that nationalizing health insurance will cut costs by reducing overhead and promote overall health by giving all Americans access to preventive health care.

What shapes us more: our DNA, or the way we’re raised? The nature-versus-nurture debate has drawn disagreement for thousands of years, and emerging genetic research indicates that the scale may be tipping away from parenting and toward biology; but not all trust the research.

Recent polls show that two out of three Americans support capitalism. But with the wealth gap widening and democratic socialist politicians gaining support, some Americans are starting to consider socialism as a viable economic and political model. Supporters of capitalism claim that no other system has been as effective in creating value, increasing prosperity, and producing the wealth that has lifted billions of people out of poverty. The free market, they argue, encourages competition and human ingenuity, values individual choice, and organizes society in a fair and just way.
