People not realising this is what's so baffling.

Narrator: The left did not, in fact, get everyone’s basic needs met because it hasn't been in power for nearly half a century. And incidentally, every time it was represented in government there were major strides in "getting everyone's needs met".

Don't believe me? Do a Google search for "most liberal/leftist US presidents", click any of these listicles and try to find the most recent leftist president. Notice how there isn't a single one more recent than 1969?

For most of you reading this, the last actual leftist government predates your parents' birth.
