I do agree that of course unmanageable debt is undesirable.
However we need to recognise that sometimes periods of debt in particular circumstances are entirely understandable.
Events in early adulthood can have a significant impact in ones a ability to manage money later on.
I am currently debt-free ( aside from mortgage) having benefited from an inheritance that has enabled me to pay debts off quickly.
Critically though the period of accepting debt allowed one of us to retrain so that we could have two incomes again that work around school holidays ( teacher). Without accepting that for one year our outgoings would exceed our incomings would have stayed probably insufficient for years.
We have no family support, a child with additional needs, have experienced redundancies and mental health crises between us. I experienced bereavement ( loss of a parent) at 19 and was left to my own devices by both father and step parent. As a result I had no help at university and no home to go to inbetween terms. Of course i worked and temper but I starter my career with debts behind me and that meant my salary went on servicing that rather than being able to save.
In the past I have had debt management plans that lasted years.
I am now debt free due to said inheritance.
However that period of debt whilst my husband retrained, we would have done without that inheritance, and we made the decision to have a year of debt in order to better our long term prospects. Without it one of us would have stayed in a low income role for longer and that would have reduced our ability to earn and accrue pension contributions for retirement. The main difference is that we have been able to clear those debts immediately, instead of over years. Overall our economic wealth will be better over our lifetime due to accepting that debt.
We have also not needed to downsize our home and therefore benefit from increased equity due to higher % value rises.
Debt can be a tool. It can enable you to increase your overall prospects.
Having said that, I am happy to be debt free and now in a position to save.
