I think it's fairly clear even in his example that not all white collar is created equal. I'm not sure how you'd divide it but certain professions like Doctors and developers are not in the same camp as management/accountants/lawyers. So, for the following quote from the article, who are the people actually necessary for "creating and delivering the goods and services that consumers want and need on a daily basis." "there is a massive shortage of blue collar jobs like truck drivers, hospitality and restaurant employees, and other employees necessary for actually creating and delivering the goods and services that consumers want and need on a daily basis."
