It certainly is.
There certainly seems to be a connection in there somewhere. Serious discontent over shortages of food certainly occurs now and again:
[quote]Polish army artillery was turned on grim workers holding out in Poznan’s anticommunist bread revolt today, a French business man reported.
Lucien Delain, of Meudon, France, arrived by automobile at Helmstedt on the frontier between East and West Germany and said he had seen the artillery firing spasmodically when he left Poznan at 9 a. m.[/quote]–“Gunfire Is Continuing in Polish City Revolt, Is Travelers’ Report,” Spokane (Washington) Daily Chronicle, June 30, 1956
And again:
[quote]Polish troops and tanks moved into three northern Polish cities today to put down rioting.
Workers infuriated by food price increases have stoned Communist Party offices, set fire to shops and cars, looted stores and clashed with militiamen in the past two days.
A Polish Radio report monitored in West Germany said the clashes occurred at Gdansk, Gdynia, and Sopot. . . .[/quote]–“Tanks Move in to Quell Riots in Poland,” Sydney Morning Herald, December 17, 1970
And yet again:
[quote]WARSAW, Poland (UPI) – Shipyard workers in the major Baltic seaport of Gdansk, where 1970 riots brought down the previous regime, went on strike today in the spreading seven-week labor unrest rocking Poland, dissidents said.
Unlike other strikes, which were sparked by an increase in the price of meat, the dissident Committee for the Social Self-Defense said the workers at Gdansk were angered over the dismissal of a woman colleague, who was fired for involvement with a dissident trade union.
“It is a solidarity strike and has a political character,” Jacek Kuron, committee spokesman, said.[/quote]–“Polish Shipyard Workers Strike,” (Dubuque, Iowa) Telegraph-Herald, August 14, 1980
But it appears that the unrest described immediately above originated with protests against meat price hikes:
[quote]WARSAW, Poland (AP) – The Polish government announced it was doubling the price of common types of meat, and 6,000 workers at a nearby tractor factory staged a one-day protest strike.
Reports from Ursus, an industrial suburb outside Warsaw that was the center of meat riots in 1976, said most of the workers had returned to their posts today. But unconfirmed reports reaching Warsaw said 3,500 more workers at a car parts factory in Tcew, in north Poland, also walked off their jobs Wednesday.[/quote]–“Meat Hikes Protested in Poland,” Youngstown [Ohio] Vindicator, July 3, 1980
And I guess that last performance (or run of performances) is the one that eventually brought down the house. I wonder if such a thing might happen in China. But for all I know, the people in charge in China nowadays may be tougher and meaner than the Polish and Russian Communists were back in the 1980s.
