Just for fun, I'll give you a tiny case study.
My daughter wanted her own flat, which is perfectly understandable.
I told her I would fund a decent deposit, as banks were a bit difficult at the time.
However, I also told her she must save every month to make sure she had a separate account into which she must put something every month, so that she always had at least 3 month's mortgage payments. That way, if she lost her job, or just hated it and had to get out, she had a bit of leeway while she found a new job. It's called "security" and is nothing to do with leveraging debt, just keeping a roof over her head.
I left it for a while, then asked her how she was getting on with her savings, given her employer had made noises about redundancy.
"No problem, I've got 6 months mortgage payments in that account, so now i can go out and enjoy myself, knowing I have that cushion".
she's now fully employed, and, as so many have these days, a couple of other jobs doing stuff online. The youngsters are not all daft! Everyone needs at least 2 jobs, preferably 3, even if the peripheral ones only bring in the bread and butter...the bread and butter to survive on, while the mortgage is still being paid...6 months is often enough time to find a new job.
Had she decided to branch out on her own, which she did with a couple of small ventures, she still knew she had a roof over her head. Those small ventures brought in good cash in difficult times, so she tightened her belt and worked very hard at them, a few pounds here and there...but she has never relied on the bank of mum and dad, and, apart from her mortgage, is debt free and enjoying life.
Of course, she might have asked the bank for funding for those small ventures...what do you think the response would have been if she had no savings and a mountain of debt?
Horses for courses...but don't tell me a debt-free model is a stupid idea.
She sleeps at night, has fun out with her friends, and works very hard at building her career without the constant nagging of bills she can't pay.
