Just one correction though: Your definition of middle class has to be super wide to call many tech jobs "solid middle class". It's not as if everyone ends up in the billionaire column, most definitions of middle class end with household income at $165k. Many in tech go over with one job. Once a family has two jobs and one is in tech, basically everyone counts as upper middle or above. With two tech jobs in a household, claiming middle class is often denying one's actual status.
