Why is "the great leap forward" ironic?

Mao had toured China and concluded that the Chinese people were capable of anything and the two primary tasks that he felt they should target was industry and agriculture. Mao announced a second Five Year Plan to last from 1958 to 1963. This plan was called the Great Leap Forward.

The Great Leap Forward planned to develop agriculture and industry. Mao believed that both had to grow to allow the other to grow. Industry could only prosper if the work force was well fed, while the agricultural workers needed industry to produce the modern tools needed for modernisation. To allow for this, China was reformed into a series of communes.
