C'mon, man. No-one is suggesting credit is bad or that you should buy your house cash. This is not a moral or binary issue, either all one or all the other. It depends.
Long term debt is for most of us an essential mechanism for acquiring fixed property, for example.
But going into debt to fund consumables is the road to ruin.
All I am suggesting is that for most young people starting out their working lives, going into multi-year debt for the capital component of their transportation costs is imprudent and unwise.
I have seen it dozens of times ... Young man finishes school or university, gets his first job, and within three months has two thirds of his nett emolument committed in hire purchase contracts, all at max ladofca interest rate. Within a year the financial stress begins to take its toll.
One in a thousand takes the long term view, drives the fifth-hand hand-me-down from mom or gran for as long as possible, saving every spare cent.
Five years later, our first lad drives his second new car (the first was pranged), pays the same percentage of his pay servicing debt. The prudent one buys a new car cash, and is putting the rest into fixed property, RAs, our some other investment. Ten years later we see the really big difference. Etc.
This ability to take the long-term view, to sacrifice immediate gratification for long-term benefit, is of course also evident in the person's approach to work and other areas of life. Usually they're your best employees, and very often fast track to senior management or end up being entrepreneurs and business owners.
They understand how to balance today and the future.
A single person starting out their working life with a brand new motorcar financed through a debt with instalments more than 10% of their take-home pay is in my experience a good indicator of someone who can't see tomorrow.
I get your point, but you are making your conclusions based on what you assume my salary might be.
