Hans-Hermann Hoppe is the philosopher of the Austrian School of Economics. Hoppe, Professor of Economics at the University of Nevada, Las Vegas, has written many excellent books and articles on libertarian/anarcho-capitalism. A standout is the sadly out-of-print A Theory of Socialism and Capitalism, available at Mises.org as a PDF download.
Hoppe builds an unassailable case for why all versions of socialism lead to poverty; from relative poverty when considering the form of socialism found in the European Union - a form that many in the US seek to emulate, to abject poverty due to the form of socialism adopted by North Korea. Only capitalism can provide for the wants and desires of the common man.
This book is clear and concise, and a worthwhile read.
