I do not agree with their economic policy, that is why I specified "Left-Libertarian." I am a libertarian because I believe strongly that government does not have our best interests in mind. They are vastly inefficient, self-serving, psychopathic, and corrupt. On both sides of the aisle. I am almost identical to the Libertarian Party platform as far as my beliefs on civil liberties, personal freedoms, and a non-interventionist foreign policy. I support gun rights, drug legalization, prostitution legalization, open borders, ending government surveillance, demilitarizing police...just for a few examples. I very much believe in limiting government power as much as possible, as I believe them to be a main cause in our problems rather than the solution to all our problems.
Where I tend to differ from the average libertarian is I believe that big corporations/banks are just as inefficient, self-serving, psychopathic, and corrupt. And just as much to blame for many of our problems. That's what makes me left-libertarian. I, instead, support an economic system, still with a free market, but built on mutual aid. For example, cooperative businesses instead of corporations, credit unions instead of banks, health shares instead of health insurance companies, etc. And I support a catch all social safety net in the form of a Universal Basic Income system which will gut government welfare bureaucracy in favor of a simplistic system that takes care of the most basic needs of all our people.
