Youre right of course in parts, It's to be expected really, I suspect (and I think it's generally accepted) many members on here are rather more mature in age and have already lived through the tough times, children and all the expense that goes with them has evaporated, and by extension od age, mortgages where applicable, aren't the millstone they were when we were younger.
Go on a e scooter forum, anything that will inevitably have a younger generation audience, I suspect you'll get the pole opposite of people's experiences.
Ask me the same question 40 years ago, I'd have told a very different story and life to the one we have now.
I don't detect any boasting smugness tbf, its just the reality people are in, we can only relate to our current circumstances. Let's face it, many of us are spending at least £1000 on a bike purely (but not exclusively ) for pleasure. That in itself is perhaps ridiculously extravagant to many people.
But the essence is, whatever your age, or financial income, frivolously spending may increasingly lead you up the path of debt. Careful choices and a bit of financial awareness may, only may, bring you security later in life, they are the simple realities .
It has occurred to me while I relate my financial position, it may be galling to someone who is struggling... but then equally, I could compare myself to someone who had done far better than me and feel inadequate...but I don't. One of the key points of the original article, don't get hung up on comparing yourself to someone else, that's one of the main contributors to people stretching themselves beyond what's financially sensible.
