There are also "left" economic concepts such as Georgism, libertarians that support Georgism are Geo-Libertarians
We are all libertarians in that we believe strong centralized governments are antithesis of liberty
The solution to this, something the framers of the US attempted, is to deny government the authority to do this. Unfortunately we did not listen to their warnings and have since at least the end of the civil war, and more accelerated since the Great Depression have removed these limits from government, have rolled back the separation of powers. altered the very foundation of the US Government and allowed more and more power to become centralized, this as enabled the very wealth and income inequality that people now want the government that caused the issue in the first place to "fix", this of course will fail but supporters of government solutions to all problems will never admit that the government is the problem...
As the axiom goes, Government: If you think you have problems now, wait until you see our solutions.
>>Fascist dictatorship is the final state of numerous, maybe most starting points.
No, most nations will devolve to fascism as a direct result of trusted the concept of democracy too much, democracy naturally lend themselves to moving more and more power into the centralized control of the majority, at which point it is short step to fascism
This is something the left in the US gets wrong very often as attempts to nationalize more and more regulation and laws at the federal level, attempts to make more and more of our system "democratic".
Federalism with a strong constitution is the way to preserve liberty, and stave off fascism, 2 things the left in the US want to tear down
