These sort of time luxury, magnitude of free/disposable income, and free cognitive load (less stress, etc.) aspects are all too frequently overlooked when shunning the working poor and now, even many working middle class Americans.
I remember the sort of stress I had first starting out simply keeping up with utility bill payment schedules to avoid late fees. I had the luxury of enough assets and steady income that I quickly setup autopayments on my credit card and never had to think about it again.
I had relatives and friends who couldn't setup autopayment because they were never sure if they'd have enough in their account or ability to pay their credit card and had to strategically optimize when and what they'd pay. The amount of cognative load folks endure juggling many of these artificial constructs makes it difficult for them to pursue and seize opportunity when it arises to get ahead.
Arguments could be made as to why some should or should not be in such situations but this is just one example. I often think about how difficult it is to fit certain necessary things in my schedule and then remember I don't ride the bus in the work which dramatically reduces my commute time.
There are many such aspects people deal with daily and it can be daunting. If you're very wealthy, a lot of these problems you can throw relatively marginal money at and the problem is solved while focusing on furthering yourself.
