Personally I think the inflation rate is calculated incorrectly (although I haven't seen the exact price comparisons).
But, one compares items that were traditionally manufactured in the USA compared to inferior quality import items, it would unfairly skew the inflation rate low. How can businesses insist that the inflation rate is less than 3% (less now?) when property prices were increasing at 5% to 10% a year... A "correction" in land prices was certainly necessary.
Personally, I haven't been in the new car market either, but my parents bought a new AMC Hornet in 1976 for $3,500. Hard to find anything for less than $35,000 now. Ok, some of the bottom line cars might get down to $15,000 or $16,000, but it is still quite a price jump.
As far as equipment, there can't be any used equipment on the market if there isn't any new equipment sold.
One of the things that happens is that there are fundamental shifts in technology. Some of it is what is popular at the time, mowers, conditioners, and etc. However, sickle bar mowers have been essentially eliminated from hay production. Thus, everyone wants to buy a disk mower. And, since the mower/conditioners were popular in the 80's, and unpopular now, at least around here, that decreases the supply of disk mowers, driving up the prices of used equipment, and probably new too.
Will inliine balers supplant traditional balers?
There are many things in agriculture where timing is critical.
One could potentially have $10K, or much more worth of hay laying on the ground, a dead baler, and rain in the forecast, and no used balers for sale in 500 miles, and be kicking oneself for not buying that bright shiney new baler.
What is the cost of redundancy? A spare baler, tractor, whatever?
I must admit that I was wanting to convert a Freeman wire baler to a string baler, but the company suggested that I should expect about $6000 worth of parts for new knotters, needles, and etc. I'm better off finding a used baler to pull parts off of, although I was really liking the idea of brand new knotters.
