The problem is not capitalism but materialism, as in the abandonment of any transcendent/supernatural value. Letting the people free to produce, buy, sell, etc, without the heavy yoke of the government on them can do wonders for the economy, but it won't save you from civilization-destroying menaces like feminism, trans-ism and many others.
Capitalism= market, basically. It's the only type of large-scale economy that really works. But the economy is not the most important thing, it's only the third most important behind culture and religion.
