People on the right are NOT saying there's no value in ANY college degrees and that people need to be prevented from going to college and get forced into menial labor jobs. NOBODY is saying that. It's apparently the product of your fevered imagination.
What people on the right HAVE been arguing is multiple related things that are bit more complex than you can apparently handle.
1. Obama's federal takeover of college loans was a BAD idea and implemented VERY BADLY. He effectively made it so any kid could borrow any amount of cash to spend on any major at any college/university. This was HORRENDOUS. It enabled the most gullible consumers (kids with little real-world experience with big purchases and, lacking full-time work experience, little appreciation of how difficult paying-down big debts would be) to get talked into huge debts by colleges eager to mop-up all that cash and willing to provide USELESS degrees in majors that would sound good (and easy) to kids. Right-leaners back then warned that this would drive-up college costs as the school operators discovered this new fountain of unlimited money, but they were derided as "anti-education". To see how dead-on the predictions of the right were on this, lookup the inflation of annual college costs pre- and post- Obama. Nobody needed to be a wizard to predict this, one only needed to understand basic economics and basic human nature.
2. Many of these useless college degrees now provide kids with no better job and pay prospects than they'd have had if they'd gone to trade schools and learned skills the country truly needs and which are in high demand (like plumbing, electrical, and welding skills). Had those same kids gone the trade school route, many would now have good jobs with good incomes and NO COLLEGE DEBTS. This has been proven true. Yes, a brain surgeon will take home more money (even after making monthly loan payments) than an average welder, BUT the average welder will find it easy to get a job wherever he wants to live, start earning a good salary at least 3 years before his college-attending peers, will not be having to make any college loan payments out of each paycheck, AND his pay will be higher than that of many non-technical degree holders.
3. Having huge numbers of illegal aliens in the country doing many jobs has pushed down the wages and benefits for those jobs, making them unattractive to American workers. This too is provably true. Americans used to do ALL those jobs, and not that long ago. All that illegal labor has also had another negative effect: it made that work, done by human hands, so cheap that it does not pay to automate it. Had that labor force not been there, there would have been a demand in the marketplace for all sorts of new automation and lots of new small American companies would have arisen to design and build robotic systems to do many of those menial tasks (particularly in agriculture) and THOSE automation jobs would have been great for American workers.
4. NOBODY of any importance on the right is talking about preventing anybody from going to college to get a good degree in some useful thing. Certainly SOME are indeed against garbage degrees (like gender studies) that will put a kid in deep debt and only lead to a job as a barista, but the last politician IIRC who actually pushed legislation to control how many people could get a degree in which fields in any given year was Hillary Clinton, who proposed this as part of "Hillary Care" back in the 1990s. She thought the government could control healthcare costs by indirectly rationing specialty care, by controlling the numbers of doctors graduating each year with degrees in the various medical specialties.
The truth is that, rather than federalizing all student loans, and taking the borrowing limits off, and then occasionally going hyper-cynical and teasing the idea of "loan forgiveness" (to try to buy the youth vote in each election cycle), what we SHOULD have done was to teach high school kids to have a clear view of not only whether they were suited to college or trade schools etc, but we should also have taught them the basic economic law of Supply and Demand. Kids needed to be shown which degrees would be in demand and thus provide opportunities and pay well, as opposed to things like "Gender Studies", "Art History", Klingon Grammar, or Taylor Swift studies where the entire nation might need a total of five or six people with the degree (in Art History... Paramount might need one person with the Klingon degree, if cheap enough, but there'll probably never will be a demand for a degree in Taylor Swift).
The idea that a kid's best interest is served by some high school coach who is assigned to be a "career counselor" a couple of hours a week telling them to "follow their dreams", aided by some college recruiter with glossy brochures showing an amazing campus who assures them that they should not worry about the costs, is simply evil and reckless and destructive.
