Why is it more facile and subjective to blame the real visible increases in consumer product and material supply prices than to blame "extreme raises in wages starting a spiral of inflation that started at the bottom of the economic tiers and has worked its way up?"

I just don't see there being any more reasonable objective cause and effect to that claim than the claim made by the commenter you are replying to. On the other hand in my own industry, prices for materials like lumber and steel have shot up massively causing major follow-on effects, and nobody at the steel mills are blaming worker salary for it. They're blaming the costs of the raw materials. And the people on the job site aren't blaming the tradespeople wages for the project going over budget, they're blaming the high cost of the steel showing up on site, late.

When workers are an issue for project delivery or budget it's usually not what they're charging, it's just availability. There are simply not enough field workers out there who can drive steel rivets or manage a punchlist. In fact, I hear rising wages brought up as a potential way to attract more people to the those field roles, because right now there are not enough people entering those roles.
