Maybe 20% and that's being kind.
I'm sort of agree with
@Hawk_4shur and
@joelbc1 views on libertarianism. It's really easy to make it sound good but when rubber meets the road and puts it into practice what does it mean?
It often means massive deregulation of businesses that have harmed, endangered and even killed people because they were not regulated enough and pursued profits above all else. John Oliver had a good segment about how Boeing's pursuit of increasing it's own stock price has endangered the safety of the flying public.
It also often means that people who are economically struggling are simply left to fend for themselves because "economic freedom" means that we don't want to make anyone pay taxes to help them. This is where the selfishness comes in. It's about pretending that you never benefited economically from having a community around you and therefore deciding that you are going to actively oppose anyone else benefiting from being in a community.
Backing out of our security agreements and closing down our bases overseas just leads us back into the isolationism that failed us in the 1930's.
Quite frankly a major problem with our country is that we under-regulate in general.
