Googling it provides a quick-answer box that states this claim and provides a source:

https://www.google.com/search?q=what+percent+of+student+loan...

92% Federal student loans make up the vast majority of American education debt—about 92% of all outstanding student loans is federal debt. The federal student loan portfolio currently totals more than $1.6 trillion, owed by about 43 million borrowers.

I think it's then pretty fair game for a forum comment to then suggest there's a causal relationship between "an entity that can print the currency that denominates the debt is backing the debt" and "this drives the price of the thing up due to easier access to funding for it".

No, it doesn't. That quick-answer doesn't even mention rising tuition costs. It's only tangentially related. The existence of government backed student loans does not in itself prove they are the main cause of increased tuition.

To prove that claim, you'd need to actually demonstrate some sort of causal relationship and have data to back it up

For example, you could make the argument that:

1. Demand is the primary cause of tuition increases

2. Government backed student loans are the primary cause for the increase in demand

I believe that 1 is almost certainly the main cause of tuition cost increases. What I haven't seen any evidence for is 2. If it's true, show me the evidence. I'm open to it.

From what this article states and the research I've done, the main driver of demand is not cheap government loans. It's the labor market. The best jobs in this country require a college degree. That is what is probably driving demand, the desire to earn a liveable wage. Not the fact that you can get a cheap loan.
