Which program was intended to overcome the backwardness of china’s economy, technology and industry

The answer is - ''The Great Leap Forward''.

The Great Leap Forward was a program implemented by the Chinese communist party, with Mao Zedong in charge, and its goal was to make China a global superpower over time, instead of being a country in the shade of the others that is struggling on every level.

China was in a bad position economically,  socially, its industry was not well developed, and also had social problems, and all of that contributed that a measure and plan is made as to how the country should and can progress and become a global political and economic player. Unfortunately for them, this measure was a big fail, and instead of making the country stronger, it actually made even more problems and put it in a worse position.

the difference is that white collar worker performs skills like worker as a scientist or well blue collars do physical work and they do services like being a cook.
