Socialism: stimulating growth at the expense of freedom

In Trump's state of the union address, he said that "America was founded on liberty and independence and not government coercion, domination and control. We are born free and we will stay free"

In response, Bernie Sanders counterargued that "people are not truly free when they can’t afford health care, prescription drugs, or a place to live. People are not free when they cannot retire with dignity or feed their families."

Huffington Post then quoted MLK, saying "This country has socialism for the rich, and rugged individualism for the poor.’ It builds on the success of many other countries around the world that have done a far better job than we have in protecting the needs of their working families, the elderly, the children, the sick and the poor."

SO WHY ISN'T LIBERTY ENOUGH?

Why aren't free people achieving affordable health (care), housing, etc.? Why do free people keep allowing themselves to be dominated by business instead of taking the reigns of their own destinies by achieving the knowledge and skills necessary to live free and responsibly without government intervention?

Could it be because of socialism that they don't? After all, why else can some drug company raise the price of a drug to hundreds of thousands of dollars except because they know there is some chance of getting some insurance fund or rich person to pay for it? And how would all that money be available except because of all the fiscal stimulus and bailouts used to re-inflate the economy recession after recession?

By stimulating growth, the socialist approach to economic governance continues to reinforce and protect the vast disparities they criticize. As long as they reinforce those disparities by intervening in a receding economy to re-inflate it with stimulus spending, the costs of such things as health care, higher education, and everything else necessary for free people to take care of themselves will remain high.

So the question is how can we go beyond socialism so that all the people can utilize liberty instead of socialism to achieve a good life, society/economy, and environment? I don't think we can even begin to answer this question until the proponents of socialism acknowledge the problem and aspire to come up with approaches to the general welfare that rely on liberty instead of social-economic control.
