Calling a CFO at a Fortune 500 company &#x27;working class&#x27; because they work for someone else is going to raise eyebrows.<p>You can argue about educational capital, but learning to be a truck driver and maintaining a clean record is capital in the same way as being an MD is capital, but the scale is vastly different.<p>The wider problem with this standpoint in the modern US is a &#x27;working class&#x27; truck driver over their lifetime may make significantly more money from capital via 401k and home ownership than directly working.  All it takes is someone living somewhat below their means and time to let compound interest takes off.  However, the benefit more from policy&#x27;s that help at the start than lower taxes late in life.<p>An 80 year old who owns their home and has 2.5 million in the bank is qualitatively very different than a 22 year old with 2.5 million in the bank and their own home.  Most obviously future returns +&#x2F;- 3%  mean little to the 80 year old and are vital to the 22 year old.<p>PS: Some people add in a managerial class who make money from other peoples capital.  But again scale is important, and pay is a huge indicator about the kinds of leverage you have. Managers making 30k vs 30m are worlds apart.
