So, let's start with the headline. "Why China built..."
Let's clear this up right away. "China" didn't build shit. Thousands of Chinese workers who work for independent construction contractors did. Contractors who are privately owned businesses. (Note the plurals all along!) The dome was designed by an engineering firm who used the materials research of various structural materials firms, and all of this was governed by an lead construction firm.
Why were none of these named?
