WASHINGTON (CBSDC) — Dr. Ben Carson slammed President Barack Obama’s signature health care during his speech at the Value Voter’s Summit Friday.

“Obamacare is really, I think, the worst thing that has happened in this nation since slavery,” Carson declared. “It is slavery in a way because it is making all of us subservient to the government.”

Carson said the implementation of the Affordable Care Act was never about health care, only control.

“That’s why when this administration took office it didn’t matter that the country was going off the cliff economically. All forces were directed toward getting this legislation passed,” Carson said.

Carson also made a comparison between Obama’s health care law to former Soviet leader Vladimir Lenin.

“Vladimir Lenin, one of the fathers of socialism and communism, said that socialized medicine is the keystone to the establishment of a socialist state,” Carson stated.

Sens. Ted Cruz, Rand Paul and Marco Rubio also spoke Friday at the summit.
