<p>Nearly all first world countries are democratic socialist, with the US being towards the right of the democratic socialist spectrum (almost capitalist) and Scandinavian countries being towards the left (almost Marxist).</p>
<p>For pure Marxist and pure capitalist societies, you’d have to go to the third world.</p>
<p>China’s not democratic but their economy functions similarly to a democratic socialist one.</p>
<p>The last first-world capitalist country was the USA in the 1920’s and the last Marxist country was the USSR in the 80’s. Neither did too well.</p>
<p>Capitalism involves vast inequalities, and huge penalties for losing your job, often going below the poverty line. Marxism involves little to no inequality or penalties for job loss, often having the government employ workers to prevent job loss.</p>
<p>Democratic socialism has medium inequality and medium job loss penalties.</p>
