For a long time, the planned economy has cultivated a consciousness that as long as it is public, it is justified. The consumption of the people may be reduced as much as possible, but in a market economy, this concept has been reversed. Government buses are the most inefficient Consumption because civil servants use cars and other people (people) come to pay. Everyone else spends money for personal consumption is a waste compared to personal consumption, because the rights are asymmetric. What is the correct understanding of the so-called "upside-down"? ['Public consumption is not legitimate, and the consumption of the people should be expanded as much as possible.', 'The right to consume must be symmetrical with responsibility, otherwise it is a waste.', "People's consumption is legitimate, public consumption should be minimized.", 'Oppose consumption by others, and advocate that consumption must be paid for by yourself.']
