As the population grows, more people buy more stuff. Local woodworkers and cabinet makers cannot possibly fulfill demand using locally sourced materials and hand tools. If everyone is to get chairs and tables and cabinets, production must be automated. Once automated, production can scale, which usually reduces both quality and cost. Instead of local wood, wood is imported and turned into particle board because its dimensions make automation easier. But now a nightstand can be turned out in less than an hour, where a traditional artisan might spend a week or more, driving up labor costs.
In other words, it isn't that people need to "rethink" what's valuable. They have already done the thinking, and they value more affordable, lower quality goods over limited, expensive ones. And I don't blame them.
