Chapter VI provides that the economic system shall rest on Sun Yat-sen's

principle of _min shêng_ (_q.v._, below). Willing to apply whatever worked best, Sun himself had no theoretical objections to capitalism, communism, state socialism, or any other economic doctrine. Hence, proletarian ownership of the means of production is not guaranteed; yet state ownership is not restricted, and is specifically required in the case of "all public utilities and enterprises of a monopolistic nature" (_Art._ 123). Henry George's influence on Sun is shown by mandatory taxation of unearned increment (_Art._ 119). Room for free future adaptation from corporative economic techniques successful in the outside world is assured (_Art._ 125): "Labor and capital shall, in accordance with the principles of mutual help and cooperation, develop together productive enterprises." It is likely that any imaginable economic system would be constitutional on this basis, provided that it was initiated by due legal procedure and without hardships irresponsibly imposed.
