Not having to spend on things that aren't important, that's some idea but, this often comes to play when you go for some of the luxuries of life. Like, trying to buy se of the best automobile brands.
I have had to track back at times on some of the items have spent money on to know which of them could have been avoided but, I'm often disappointed. I hdy recall anything neither do I find one that could have been avoided.
In the end, we still find means to survive and that's human nature.
My pattern is not too far off because the right way can have a small impact on the problem of dealing with hyperinflation conditions and for me trying to live frugally and spend on something important is enough in hyperinflation conditions.
Sometimes people who are financially healthier do not have a big impact on this condition and as you said, living in luxury and spending on things of great value is their lifestyle.
To survive we have to have a way and when our finances are unstable our life will be much more difficult, so trying to live frugally is a step that needs to be taken.
Avoiding unnecessary purchases is important because when someone has money, they should think about how that money can be more productive and that is how smart people handle financial problems.
