I’ll bet this has something to do with SANY (3-1) and CCP. SANY makes concrete pumpers. Its president is CCP crony. Changsha already has tons of vacant high rises. Mao’s old stomping grounds. 100+ degree summers. Uffda.
This brings to mind a couple of points about another socialist wriggle:
#1) During the great leap, Chou en-lai had the task to taste and approve a green roe like substance called chlorella, which grew in urine and contained some protein. According to Mao (2005) Chang/Halliday:429 this excrement provided a high proportion of the urban population’s protein;
#2) about the phosphate needed for Obama’s algae, during the same period with fecal matter in high demand, fights broke out when communal toilets were raided by rival villagers (ibid:422).
Bastiat’s Negative Railroad explains the calculation and blessings of destruction. Bucanan/Tullock pick up on this math in The calculus of consent. Rent seekers gain more proportionally than free traders lose. h/t Lucid Discourse 4c negative railroad math.
