It is very easy cherry pick particular expenses and demonize them. Also many grandparents are paying for these expenses and do you even have data on how many of these families are going "multiple times?
While the author’s mathematical projection correctly illustrates the power of compounding, it relies on a "vacuum" model of finance that ignores the structural economic barriers facing the average American. By assuming a consistent 10% savings rate and an optimistic 8% annual return over 40 years, the argument dismisses the reality of stagnant wage growth, rising healthcare costs, and a national personal savings rate that currently sits far below the author's hypothetical threshold. As commenters like Adam Starry pointed out, a $3,000 monthly income—after mandatory taxes—leaves roughly $2,200 for all living expenses, a margin so thin that a single emergency or a "life blip" would necessitate liquidating those very investments the author relies upon. Ultimately, the author proves that math is easy, but fails to account for the fact that for many, the "discipline" he suggests is a mathematical impossibility when basic survival costs consume nearly 100% of take-home pay.

No many can't. It is very clear from household data and it isn't because they don't understand compounding or other such concepts.
