Why did Romex get so expensive?

Why did Romex get so expensive, Romex got so expensive due to rising copper prices, increased demand, supply chain disruptions, inflation, and manufacturing costs, with copper being main cost driver. Copper prices surged due to global demand for electrification, electric vehicles, renewable energy, and construction boom, with copper being essential metal, with price of copper rising from 2 dollars per pound to 4 to 5 dollars per pound, doubling Romex cost because Romex contains copper conductors. Supply chain issues during COVID pandemic caused shortages and logistics costs, with factories shutting down and transportation delays increasing prices. Housing construction boom increased demand for Romex, with more houses needing wiring, pushing prices up. Inflation increased labor and material costs for PVC jacket and insulation. Tariffs on imported copper and materials also contributed. So Romex got expensive because copper commodity price increased dramatically, demand from construction and electrification outpaced supply, supply chain disruptions, and inflation, with 250 foot roll of 12/2 Romex going from 40 dollars pre pandemic to 100 to 150 dollars during peak, now somewhat lower but still higher than historical, with larger gauge like 10/2 and 6/3 even more expensive due to more copper, making electrical work more costly.
