Insufficient demand has caused overproduction, while layoffs and wage cuts have caused the income of low-income groups to continue to fall, demand has become weaker, and overproduction has become more serious. According to the above paragraph, the following statements are wrong:. ['Overproduction is caused by insufficient demand.', 'Overproduction is because production is not properly organized according to consumer demand.', 'Expanding demand can alleviate pressure from overproduction.', 'Over-production and under-consumption are mutually causal and repeatedly intensifying processes.']
