When I worked in China in the mid 70s, they cast a concrete pedestal for the boiler stack about 2 feet two high. They had jackhammers and excavators to use, but nope. They have a dozen guys crude chisels formed from soft steel rebar and put them to work chiseling it down. I was flabbergasted. Whenever I heard the claim that “China has no unemployment,” I knew the real reason why.
The site I was at (mining site in West Papua New Guinea) had to take in lots of workers from the cities. Sort of a paid welfare type thing. Two guys would be hosing down a 50’ x 100’ concrete pad all day long.
