Yes indeed!
"Discount" in the form of China's government-sponsored infrastructure and vertical integration efforts, such as purpose-built hubs connecting upstream and downstream suppliers with accessibility to rail depots and seaports, are not yet common in other countries with lower labor cost.
What we are seeing is the end-product of a massive distributed project between Chinese producers (with support by various levels of the local, provincial, and the central government) and major multinationals over the past several decades, and some stakeholders are married into the paradigm.
I think the pandemic also revealed to multinationals that the choice may not be a simple binary choice between China and other low-cost jurisdictions, but whether the efficiency-focused paradigm as a whole should be the path forward.
If multinationals opt to balance between resiliency and efficiency, then the choice may actually be contingency suppliers in North America or Europe (can you imagine the cost).
This is now at the cutting edge of supply chain discussions (with significant implications on inflation), for as you pointed out, the current paradigm took more than two decades to build, and it is entirely focused on cost and efficiency, with an assumption that it would be resilient. The pandemic argued otherwise. How do all the stakeholders pivot from a 30-year project into something else, and would the gains in resiliency be worth the price? This is exciting times.
