If you can afford to put aside almost 100k a year and still live comfortably you are decidedly not in the class of people for whom saving is, if not an impossibility, a luxury.
We're not just talking about Pratchett's Boots Theorem[1], but also the fact that such people are quite literally only one or two paycheques away from total disaster. These are the people who can't afford to save because every penny is spent on merely surviving, and they can't amass the bare minimum amount of wealth it would take for them to be able to lift themselves out of that situation.

Many people are 1-2 paychecks away from total disaster, but they never take the step to make a change. It can certainly feel impossible. But the reality is "merely surviving" has a broad usage. I know lots of people that are living paycheck to paycheck, but have the iPhone X.
Here is a thought experiment. Lets assume that the minimum required to live in a given place is $20K.
So now you have two people, one makes $30K, the other makes $40K. How much more does the second one make compared to the first? Twice as much. At $30K, you have $10K disposable. At $40K, you have $20K disposable. And someone making $60K is making four times the disposable compared to $30K.
Once you get above cost of living, everything gets easier.
Good luck getting anyone to lend you that kind of money if you're actually poor.
Someone who is able to get deeply in debt basically by definition has access to money. They would not be granted loans otherwise.
