I completely agree with you. There is a culture of acceptance that debt is inevitable and normal and that it's just fine. It's not an attitude that was there even 20 years ago and it's dangerous. There's obviously a difference between good debt (education that will lead to higher income potential) and bad debt (consumer), but at the end of the day, it's still an impediment for moving on to the next phase of your life. Young adults are being crippled by debt loads; if you each owe $50k, how are you supposed to save for a house, start a family, etc? I know not everyone wants those things, but it's delaying them for almost a decade for those who do. It's taking more than a decade for people to get out from under student loans.
I wish it was just tuition that's doing it, but it's not. It's people living well beyond their means. People get used to being able to spend the way they could when they had a part-time job and parents covered all expenses. The reality is that most won't have that kind of discretionary income again until they get to my age and the house is paid for, childcare expenses are gone, college savings are done, etc. It's really important for people to adjust their lifestyle to their income and expenses, but very few do. Many spend every penny they make and then some all the way along and never get over the hump and get to enjoy some debt-free, heavy savings years. There are vast numbers of people going into retirement now with mortgage and other debt. There's no happy ending coming for many of them. Getting old isn't fun regardless, but old and poor is much worse.
I cannot tell you how many times I've heard 'I wish I'd saved more and started earlier, I just didn't realize...' somber realizations from people. We've culturally shifted away from being debt-averse to being debt-accepting, and it's a troubling trend.
Most of you here are still very young (by my middle-aged standards) and it's nowhere near too late for you to shift course. Making and sticking to a budget (that includes fun money for things like makeup, but not at the expense of savings) is a habit that gets easier over time. No matter what your budget is for makeup (I had many years when mine was perhaps $100-150 mostly from gifts), there are still ways to make it stretch and have fun with it.
