I would struggle to define a truly useless degree though. That's what I'm pushing back on: that learning from our past mistakes, taking in different perspectives from other times, places, and cultures, and learning not only to learn, but to interpret media and think critically, are tremendously important to a healthy society. What you call "frivilous", I would call low-earning.
I'm not saying failed entrepreneurs should be bailed out, even if (through bankruptcy proceedings) they de-facto are. To your point though, they're given tax breaks by my government [0], which aligns with the goals we seem to have agreed are important and good for society at large.
Small businesses are given assistance when starting out and financially vulnerable; financial assistance that is paid for by all members of society, as we all reap the benefits of a stronger economy when they succeed. I'm not sure how one defends not extending the same courtesy to students.
