Those who support the Republican brand seem to use the phrase "far left" and "left wingers" to describe everyone who disagrees with the dogma they hold true. Since it makes no sense to use these phrases to describe ten of millions of Americans, maybe one of them who uses these phrases would describe the beliefs those who disagree with them hold.
That the phrases are used interchangeably with "Marixts, "Communists", "Socialists" and other such words as pejoratives, and it is likely these economic theories are not understood and are not differentiated from political theories of governance by their users, I expect any of them who attempt to answer this question to default to personal attacks and or idiot-grams. But we will see, maybe one of them will actually think and respond substantively.
The far left wants the maximum number of people to be dependent on the highest level of government possible. The overall goal is an attempt to create a system where those dependent on the system will vote to perpetuate the system, the system of course being run by the leftists who advocate for said system.
Its control. Control at the highest level by people as unaccountable to the public as possible.
What happens when we run out of other people's money to spend??
