yes, taxation. I argue against the defunct "neo-liberal" idea that the basic requirements of human civilisation are best performed by unregulated corporations who exist for private shareholder value in the short term. That is free market ideology. I regard what used to be called a "mixed economy" as a better principle - government sets policy objectives through democratic political processes where money does not do all the talking, and regulates private markets accordingly, thereby reducing harmful externalities, and pursuing positive, sensible, societal ends.  I do not see the relevance of Venezuela, which is not even a democracy. On cars, the mixed economy is working wonders (USA - which is a mixed economy despite the myth, and Japan, Germany and others), as auto makers move to electric cars, in indicative policy environments and regulation to render the internal combustion engine at long last obsolete, along with the fossil fuel industry basis for mass transportation.
