No, Western economies grow on financial speculation built around the sheer number of buyers/consumers. Basically, Western economies are built around a massive financial bubble driven by global investors who see the West as either a safe-haven for their money, or the only place to invest their capital since third-world countries don't have stock markets or other financial products through which to grow their money passively. Beyond the stock market, crypto, and other ponzi-schemes, the other way to for foreigners to bring their capital to Western markets is through real-estate and tourism.
All of these financial schemes require a constantly expanding injection of capital otherwise everything collapses because none of it has any intrinsic value.
