The first problem in the wage system that needs to be solved is the above-mentioned problem of "iron rice bowls. *1 If these "iron rice bowls" are not broken, it is impossible to thoroughly implement distribution according to labor. This is an ingrained problem that cannot be easily solved. In the past, comrade Liu Shaoqi advocated a two-tier system. Newly hired staff and workers were to be told that they could be fired, promoted, or demoted. And this system was to be extended to existing workers after a trial period. Regrettably, it was not adopted because it was criticized as revisionist.
