I've thought about this for at least 15 seconds, and this remains mysterious to me. Could you explain, please?

Sorry for being salty, a bit hyperbole perhaps in the 2:1 numbers.

I draft and write some code for construction companies and personally saw layoffs and not taking work due to increased material costs. The structural companies we worked with similarly did a few layoffs. The average pay of these jobs was 60k+.

Manufacturing of steel is very competitive and I haven't seen the American steel drop in price. I can't personally imagine it adding more than a few thousand jobs since it's so competitive (thin margins) and you would have to add a ton of production to add one job.

Meanwhile, the profitability of building a building is a direct feed into whether buildings get built. A building not being built directly led to laying off about 100 field guys for us.
