From my perspective the biggest thread to western lifestyle is the reliance on cheap labor in Asia (production) and Africa (mining). Their minimum livable pay might rise due to food shortages, need for AC etc. That could have a major ripple effect on many product and service prices. But maybe we will have even better automation by then so we can trade opex for capex.

But I only have shallow knowledge of the major supply chains, maybe someone with a deeper understanding can chime in.
