I don't believe this. It is contrary to human nature.
What is destroying the West (Jews/Proto-Jews + Goy Slaves) is their own wealth. That is what causes every problem. They become contented and they invent problems, because people always believe they have problems even if things are perfect.
This means that yes, the West is killing itself, but for them to address this problem they would need to induce economic collapse. They need to instill work ethic, increase birth rates, decrease education, and basically make people suffer too much, be too tired, to go off on these wild fucking tangents about every little imaginary problem under the sun.
While this induces a greater level of social stability, everyone is an "Ally in suffering", they're all fighting the war of poverty together, in order to induce this, the West must cripple their economy. This is contrary to the instinct of the Jews which is just to amass as much money as possible, as money is functionally power which can be used to make more money.
Opulence and luxury are what are causing these problems. This means the Jews would have to sacrifice their own net worth, their own money, their own success, and thus their own extent of global power in order to save their own society. It's unlikely that they can overpower their own greed to this extent.
The west will keep glutting itself, killing itself with it's own success, because the Jews in charge cannot understand that too much success creates problem, just like too much heroin causes problems.
Sure, morphine is very useful in medicine, but it can also be abused to a great extent. The same is true with capital wealth, because the more successful you are, the more educated and jaded your population is, and thus the more indignant, volatile, spiteful, anti-social, narcissistic, and self-serving they are.
