If I’m right about all the trends, running since 1945, are going into reverse since 2008, then yes, artificially cheap metals should reverse. I remember often buying 4X8 foot sheets of steel, cheaper than 4X8 foot sheets of plywood.
Plywood should be cheaper than metals, because plywood grows on trees. I remember steel at .20 cents/lb delivered. Copper today at $2.65/lb. is unrealistic. Nobody will sell you copper for retail only $2.65. $12.00/lb Copper is more likely. Cheap compared to steak these days, also $12/lb.
Its amusing TPTB’s objectives starting after 1975-8 were artificially cheap materials and labor. After decades of success, THESE days they are trying to avoid a deflation situation. A reversal of the past (1934 to 1971) inflation trying to reverse? There was a long term drop in commodities prices 1980 to 2001. (killed supplies)
Then climbing prices after 2001 for about 12 years. (inflated supplies) I think it would be interesting to see a 35% tax on imports. All the crap we have around the house would be more sellable. The way it is now, imports are so cheap our used stuff is worthless.
I recently heard about a house that got sold, they put a big dumpster in front, and dumped all the nice interior furniture. Perfect stuff. Dining room living room bedroom etc. Imagine your furniture gaining value? Because imports are not affordable?
