Although I'm an independent, I come from a family of Republicans. All of us were expected to go to college. Some attended top universities, some have advanced degrees, etc. The value of higher education was never questioned. At least not until recently.
The problem is that colleges are losing their practical value. A gender studies degree, for instance, is great if one aspires to be a store clerk, but it's unlikely to provide the skills one needs to get ahead in life. Even the trades are more lucrative and provide a better standard of living. It wasn't always like this.
Unless my child plans to go into a STEM field, I will encourage them to explore other options. At the very least, a healthy young adult should be financially self-sufficient. Anything that detracts from their ability to pay their bills or self actualize, anything that keeps them slave to the state (think student loans for a major with low ROI), is simply unacceptable.
I see similar sentiments among my Republican family members and conservatives in my social circles. They're not anti-intellectual. They just want education to be worth something. Say what you will, but a debt-laden degree in gender studies is not as valuable as an engineering degree, or even as valuable an entry-level trade school certificate.
There has been a longstanding bias in favor of leftist ideology on college campuses. Much of that was tolerable by remembering that opinion is just that... opinion. At least we could agree on most of the facts. Strip away the practical fact-based value that even the most obscure college degrees used to to provide, however, and all you're left with is a bias that conservatives disagree with... and possibly a kid that won't "launch". Is it any wonder that they perceive this trend as bad for the country?
