>We need publicly subsidized apprenticeships to replace the assumed role of the outrageously expensive 4 year college degree as the primary means of acquiring skills for the modern labor force. There is a place for higher education - [...] - but it cannot be expected to be the sole gateway to the middle class.Unfortunately, your apprenticeship idea does not address a key driver of why college institutions act as gatekeepers of desirable employers. It's not so much the "training" but more of the "signaling".[1]
As a thought experiment, let's pretend that the USA de-emphasizes college and promotes apprenticeships. The USA has roughly 3 million high school graduates every year. It's safe to say that most of them are not really interested in college purely for the "skills", or "well-rounded education" including Shakespeare and Calculus III. They'd rather just earn a middle-income salary right away and college is just that "hoop to jump through" to make it happen.
Well, businesses like Google, Ford Motor, Goldman Sachs, etc are not going to be interested in dealing directly with a vast sea of undifferentiated high school graduates to offer internships. They need a pre-selection process. Therefore, a new "clearinghouse" institution would naturally emerge in the marketplace to "evaluate" (test) and "filter" (rank) these hopeful apprentices. (Perhaps Donald Trump could create a spinoff business to do just that.)
Once the clearinghouse is in place, the hopeful candidates will want to demonstrate "talent/smarts/whatever" so they get the best internship offers. That will then lead to tutoring, coaching, preparation, etc and all those services cost money.
Because of how humans work, we'd just be replacing variable $FILTER="college" with $FILTER="clearinghouse+coaching". That new model may cost less overall to society because C+C doesn't spend 4 months dissecting Shakespeare but let's not kid ourselves that this new model is "more fair". A future complaint would be, "I took out a $20k to pay for clearinghouse coaching but instead of landing a coveted apprenticeship slot at Google Inc, I'm a barista at Starbucks. It sucks because The Whole Point of the apprenticeship system is to TRAIN me!"
You see, the core problem remains because companies don't want to "waste internship training" on poor candidates. Everybody wants the best of the best and apprenticeships don't fundamentally change that human desire.
