Because our mind is setting on how much we're going to spend depending on our budget. If you're earning low, it's also going to make you adjust for what you're going for the expenses.
It's about how we manage our finances and that's why the high earners are also adjusting their lifestyle when they earn well compared in the past.
I believe, you will agree with me. Because when a person increases their financial income, their expenses will also increase. However, there is no exact guideline that one must always save. Rather, steps should be taken according to the situation. I can say from my real life experience. My monthly earnings are the same as before, but the prices of daily goods and monthly expenses have increased. Therefore, it will not be possible to save as before.
So, if financial income does not improve or increase, saving in the current context is almost difficult. Because the prices of everyday items, clothing, vehicle rentals, everything has increased. And excessive inflation has occurred, resulting in no profit from investments. Therefore, one should not be encouraged to change their lifestyle.
That is lifestyle inflation when someone received an increased salary. There's already a distribution of that increase on their minds.
And whether they'll spend it in hobbies, luxuries or recreational, there's something in their minds on how they're going to spend it.
There's no rule that someone always save, that's true. But it will be a practice that person will realize that it should be part of their routine when they have left with no money despite of being a high earner because no one is there to save them.
Well, to each their own. If they can sustain their lives the way they live it, we're all free to do our things based on our capacity even it means being broke again because no one forces us to save and invest but only when we have faced financial trouble again.
