That doesn't exist and at the same time shows how (sorry if this sounds harsh) naive you still are. Especially the automotive industry will soon have to row hard. Layoffs are not unthinkable even at the industry leaders. How long have you been earning the 3800?
Okay, if you want to put it that way: no job is secure. But our job is more secure than many others. Still, quite a few people manage to get a loan. Sure, with equity. For that, they pay, for example, an installment of 700€. We without equity want to pay about 1500€ for it. We have been earning the 3800€ since June. And no, we don't want to "squander the big money" now because it is an unrealistic amount for our age.
