That's effectively what we've been doing for the past few decades. And the result is as shown in TFA: a generation of adults who will avoid marriage like the plague, because they've seen how toxic the results can be.
In one extreme instance the parents had divvied up the house with dad ending up in a quasi-finished basement like an unwanted old dog. If they ever crossed paths it was an instant war.
Fortunately divorce has become much more acceptable since those days (this was in the 80s). Back then people would stay trapped in an unhealthy marriage 'til death do us part'.
2013 was still suffering from the after effects of the great recession that caused massive unemployment and a incredible increase in suffering.
How are current economic conditions worse than two of the greatest crashes in US history? YoY inflation is drastically slowing and unemployment is at record lows.
The economy is doing pretty goddamn amazingly right now
My understanding is that economic conditions for Blacks are not significantly better than those of Whites and Asians, and are probably somewhat worse.
Which suggests your hypothesis is not backed by data.
I'll present most of FL as an example. During those crashes, one could still subsist on 2 typical incomes. FF to today and basic expenses have skyrocketed; it takes 4 typical incomes to live tight. Worse is that expenses are still climbing fast.
The economy may be spectacular for some folks but it pales against the expenses faced by most folks.
