Materials and Labor are certainly a factor, but the oligopoly of very FEW suppliers needs to be "broke" to get to back to "fair market" pricing. These few mfgs. have consolidated the market over years (bought out others, limiting production runs, etc.) while also blocking imports these last three years or so.
So the question is will NEW mfgs. enter this market (like Wolf and other off-shore makers did a decade ago) and by doing so, "push" the current FEW suppliers (selling at PREMIUM pricing today) back to something called "fair, open competition". When this happens, we'll see components back to reasonable pricing in a FAIR market. We haven't had that in the last 4 years or so.
I don't pretend to know when it might happen, or if it will. But when you have 3-4 primer makers all drinking $500 pours of scotch in DC with legislators blocking MANY imports (*that would love to come into the US) it's what it is today.
Don't pretend they were ever hurting when they sold 1k primers for $35- they were making money, but now they are printing it.
