Here is a list of universities that have closed down since 2020 due to financial problems.
How could someone get caught if they claimed to have graduated from one of these universities? There is no department there to call and confirm that they have or have not graduated from there. Is there a way for a prospective employer to find out?
The declining value of a university degree compared to their ever-increasing costs combined with societal changes after the Covid-19 pandemic and gen z simply being a smaller generation than millennials have led to declining enrollments in universities.
However, not all universities have had this happen to them. Big name and highly prestigious ones like Harvard, Stanford, Cornell, etc. have actually seen more applicants, lower acceptance rates and more donations. Even big name state schools like Ohio State, Michigan State and Texas A&M have been doing fine with reputations that are still strong if not as strong as the ivy league schools and trivial things like well known athletic departments to draw in more students.
Also, I don't see anything wrong with lying to liars. Employers lie to employees all the time, starting with the first interactions with them whether it is a call back, speaking at a job fair, a recruiter, etc. I say lie to them for your benefit because they lie to you for their benefit and see nothing wrong with it.
