The real breaking point in Christian civilization was an actual creation of Judeo-Christian civilization by Henry Ford, who introduced 5-day working week in 1926. Up until then the Jews and Christians were distinctly different in their lifestyle and working habits, but since then this difference was superficially obliterated.
Judaism and Christianity mixed together into some form of culture may look like an astounding achievement of fundamentalist Protestant and an avid mason, that Henry Ford was, but this homunculus does not have life of its own and is simply piggy-backing on his system of mass production; its life will end and is ending with the closure of Fordian expansion.
One may easily make the case that Judaism and Christianity are divergent in the very fundamental point of individuality and its relation to the Divinity, and these differences are not properly reconciled, but seemingly forgotten. Well, they are manifesting themselves right now as the culture tears itself apart.
Henry Ford also began the epoch of managerialism, which indeed eats itself at the end, as James Burnham has predicted (Suicide of the West: An Essay on the Meaning and Destiny of Liberalism). The meaning of life, together with responsibility for one's own destiny was removed not just from the lowly working class, but from the middle class as well - and given to the ever growing class of managers - who mush up the individual responsibilities with rights into something both mass manageable and mass reproducible, which is showed down the throats of the masses in a shape of advertisements and propaganda - which again, in a new world are virtually indistinguishable from one another.
For the manager Telos is an anathema, the whole meaning is within the managerial procedures, which need to be optimized, that's all; perfectly optimised procedure is the means to an end; this applies to the state policies as well.
Under the Fordian managerial principles, the individual workers are not to be encouraged to excel and achieve the best of their own capacity, - nope, Ford and his predecessor Taylor were not interested in fostering individuality except the top manager individuality. The average worker or citizen were to carry the process, smoothly, not too fast, not too slow that's it.
In exchange for individuality sacrifice the worker would get the fatherly and motherly care of the top management, down to minute needs and the common human quirks. Plus the most obvious bonus of mass production - virtual elimination of scarcity in every and all areas of human life that allows mass production and managerial optimisation. Abundance of goods, that is attributed to capitalism is not really a feature of capitalism, it is a byproduct of Fordism.
Sure, the New Deal expanded Fordian innovations (which were seen as inhumane by many) from one albeit large private enterprise to the scale of the whole state (not just American, many other states have followed the suit, Germany and Italy even earlier than the US).
This paved the road to the current situation, and the states keep digging the hole, which indeed seems like an abyss right now
