I see the American education system and corporate media have failed you as they has so many others.

The Dems are capitalist; this alone puts them in the right wing of the political spectrum. Granted they are generally not quite as far to the right as Republicans, but the difference is much smaller than what their rhetoric suggests. Both are also on the authoritarian end of the scale, rather than the libertarian end. Again, Democrats are more moderate here than Republicans, but only slightly. They have actively resisted any attempt to shift the party left.

Genuinely left-wing political views have almost no presence in mainstream American politics. Bernie Sanders is the exception that proves the rule, and even he is, at best, center-left.
