Let’s not pretend that just because you learn a little bit about how to manage your finances it gives you the right to judge how people spend their money.
You look at them and think why do they spend so much on holidays or gadgets.
How do they maintain this extravagant lifestyle, whether they will have enough safety net taken care of.
The truth is that you are not them. You and they are each unique.
The problem is what you deemed as wasteful is very precious to another person just because you don’t understand it.
