I will try and explain it. There is no country that is purely capitalistic or purely socialistic. For example, Sweden, Norway, Denmark, France and other Western European countries utilize a mix of Socialism and Capitalism. The United States also utilizes a mix of Socialism and Capitalism. Things like public schools, roads, fire departments, police departments, social security, and Medicare are "Socialist" programs.
Someone with a similar perspective to mine believes there are more things that are currently run by the for-profit system in the U.S. that are better suited to the socialist model rather than hoping that the profit motive will produce adequate and affordable vital services such as health care. For example, expansion of electrical and telephone service to rural areas was only made possible by the use of a socialist system to fund the services as the private sector saw no profit in it. Another example would be Air Travel. Modern countrywide air travel is only possible because of a socialist system that was created to build airports in smaller cities and rural areas. My current belief is that we are currently in a period of forced population migration to urban and suburban areas because the government is no longer willing to fund vital services in rural areas like they have in the past. (I will expand on this point if you desire)
The bottom line is a lot of people (myself included) don't think our mix of Socialism and Capitalism is optimal here in the U.S.. I believe the mix needs to be more like it is in Western European countries. In fact, I think we have created a really perverted mix of capitalism and socialism in the U.S. Profits are strictly private but losses are often socialized. We have bailed out the auto industry twice now, the banking industry and the airline industry. Yet, collectively we don't share in the profits of these bailed out industries. The private U.S. healthcare system is currently subsidized by the Federal government with ever-increasing yearly costs to stave off market failure for just a little longer. Any business enterprise of any size nowadays thinks it is entitled to State and local tax dollars for simply locating their business in that locality. I recall when people here bemoaned AOC opposing Amazon locating in Queens. To me, that is the ultimate example of the perversion of capitalism in this country. How in any way shape or form is it capitalism to have the government spend ten million dollars to build the richest man in the country a private helipad?
In 2018 there were 60 fortune 500 companies in the U.S. that didn't pay any income taxes on $79 billion dollars in profit. Not only did they not pay but they collectively received $4.3 billion in tax rebates. In other words, these freeloaders didn't pay a dime for the massive amount of government services they consume and in return for their freeloading, the government wrote them a check for $4.3 billion dollars. What benefit does the taxpayer get for their forced investment in these private enterprises? Oh, that's right they get the obligation of covering their losses if they fail. Given all of this, do you think our system here is the U.S is a capitalistic system?
