The US is a corporate oligarchy ‘socialist state’ because corporations get everything they want. They are the ones that dictate laws, policy and just about everything else that affects you, and not your Local, State or Federal representatives. They are merely puppets that carry out the will of this ‘elite’. Nothing more.
State Monopoly Capitalism:
“The main Marxist–Leninist thesis is that big business, having achieved a monopoly or cartel position in most markets of importance, fuses with the government apparatus. A kind of financial oligarchy or conglomerate therefore results, whereby government officials aim to provide the social and legal framework within which giant corporations can operate most effectively.” - Wikipedia
Basically this is favoring the rich and not holding them accountable, even for egregious crimes, while controlling the people using low wages, prison for non-violent crimes and small infractions, and while suppressing their vote and protests. Either wealth will be regulated for the benefit of the people or the people will be regulated to serve wealth.
"Monopoly Capital:
An Essay on the American Economic and Social Order is a 1966 book by the Marxian economists Paul Sweezy and Paul A. Baran. It was published by Monthly Review Press. It made a major contribution to Marxian theory by shifting attention from the assumption of a competitive economy to the monopolistic economy associated with the giant corporations that dominate the modern accumulation process. Their work played a leading role in the intellectual development of the New Left in the 1960s and 1970s. As a review in the American Economic Review stated, it represented "the first serious attempt to extend Marx’s model of competitive capitalism to the new conditions of monopoly capitalism." It attracted renewed attention following the Great Recession." - Wikipedia
Example:
“This is monopoly capitalism in action,” said Marion Nestle, author of Food Politics and professor of nutrition, food studies and public health at New York University. “Whenever Amazon takes over more and more and more of any consumer area, that gives consumers less choice. And now it’s food.” - [truthout.org]
Political implication:
“Ever since monopoly capital took over the world, it has kept the greater part of humanity in poverty, dividing all the profits among the group of the most powerful countries. The standard of living in those countries is based on the extreme poverty of our countries.”
— Che Guevara, 1965 -Wikipedia
