Is capitalism enshrined in the U.S. constitution?

The USA Constitution doesn’t really endorse capitalism. It’s a description of the government, its branches, how it works, and a list of individual rights. 

I ran away from a communist dictatorship when I was 14, landed in a refugee camp in Europe, and had time to think and discuss the topic with a very diverse group of people over the years. 

Capitalism, socialism, communism, and other systems are not necessarily linked to democracy or dictatorship. Communism concentrates power, puts a smallish and very fanatic elite at the top, and therefore it ALWAYS creates the conditions for dictatorship. 

Capitalism, if allowed to function with monopolies, cartels, and corrupted government officials, can create the environment for oligarchy and autocratic rule. This is what we have seen in Latin America until democracy seemed to be gaining ground at the end of the 20th century. Capitalism is entrenched in the USA because it has worked extremely well. As far as I can see, it is also creating the conditions for oligarchy to emerge. I have doubts the system will correct itself unless the people focus more on electing honest politicians rather than so many bullshitters. 

On the other hand, communist systems self correct by imploding or moving into Neo fascism, or whatever you want to call that abomination the Chinese use. Overall capitalism is much better than communism.
