That's supply and demand. Our first computer cost $2800.00 1997 dollars. We had to order it out of a catalog, on the phone, pay shipping, insurance, etc. 4 years later it was so outdated it was almost worthless. I can go online now and get one with 100X the power/memory for under $250.00, free shipping. OTOH, a share for a JD plow that used to cost $11.00 costs over $85.00 now last I checked. A $100.00 tractor tire in 2000 now costs $450.00+. It's not all inflation. It's supply, demand, etc. I'll give you the ultimate example- chicken wings!!! Used to they were the part that was ground up for dog food. When they first became somewhat of a "thing", I could get 100 ready to eat from a local restaurant for around $18.00. Now they're pushing $1.50 each!!! The demand is high, there are still only 2 wings on a bird, so the supply is limited. Even 3 years ago the good ones from our local pizza shop were about 50 cents each!
To add to this, there is also the concept of "economies of scale," the sense of which assumes that the more you make of something, the cheaper you can make it. Computers (laptops, tablets, phones, "chips," in general, are all made by machines today - somewhere else and in VAST quantities, so there are a number of reasons a computer today is so much cheaper than one in the nineties.
Computers have regressed some too, being emasculated
However, if you do not accommodate a large increase in production, but rather over-tax your resources too much for too long, it will bite you. Paying overtime doesn't dig into the margin as much as managers would have you believe either. You are typically not going to see commensurate increase in benefits, like health care, vacation, etc.
COMPETITION is absent in all this as well. If there are no (and there aren't) competitors ramping up production also, you have the market cornered and THAT is NOT "capitalism" in the sense which a lot of people use the term in this context. I'm not talking about ideas expressed here, but this forum is a small percentage of a small percentage of the market in question. Anyway, a total lack of competition is not letting the market "self-level" or "seek balance" naturally. Whether this is by design or bad luck doesn't matter - it is what it is.
Ol' Adam Smith's invisible hand" is shackled to a wall in a basement.... somewhere. This market is being controlled unnaturally, so many of the common concepts and theories of capitalism or "good business" simply do not apply in a traditional sense, which is a clue that something is actually
wrong.
Not that letting the free market do what it will (laissez-faire economy) but that is is being prevented from doing what it will.
