All those things add up to a couple hundred a month, let's be extreme and say it's $1,000 USD/month. That amount will never move you up in the socioeconomic ladder. You're two-three orders of magnitude away(!).
"But it adds up" could argue the midwit, "why don't you just get a job that pays you more", "just invest", "why didn't you buy bitcoin in 2010", "why don't you just buy the winning lottery ticket". I wrote all those in order of increasing stupidity. Not aimed at you @merth, it's just stuff that I've actually heard.
Nobody who is wealthy these days got there by skipping Starbucks and instead throwing that dollar in a jar. Nobody.
You need to cross a threshold of (income/purchasing power) to be able to start building things that matter. It's extremely difficult these days because the denominator there is almost zero.
As TFA states, people who have not experienced poverty have ZERO idea of what it is like.
It's true that it may not help a lot if you're "missing $40,000 a year, every year, forever" which apparently is the article's definition of poor. Unfortunately we're not told what they would need such an amount of additional money for exactly.
On the other hand, maybe going from "missing $40,000 a year" to "missing $28,000 a year" is enough to not be poor anymore? It's difficult to understand the author's idea of the boundary between being poor and not being poor.
Saving that $1000 or even $100/month means you might be able to get your car fixed when you need it, which might be the difference between keeping your job and getting fired/forced to quit. It can mean eating dinner every night, giving you better mental clarity and better sleep quality which can improve every part of your next day.
I think, "poor" is bigger than what the author wrote(ie that poor people have already cut out every extraneous expenditure). For every class, there are people with good financial hygiene and people with poor financial hygiene.
My first job out of college I earned more than both of my parents combined and I felt pretty guilty about it for a while. Then I started earning 10x what they made while doodling on a computer all day, and the work:money conception lost all meaning to me.
I agree, but you should do both I think, increase your income and decrease your expenses.
