That is rather a false equivalency tbh - upper end LTDs are killer guitars with high-end specs. But yes, their prices have surged, and it has a lot to do with, I think, the line of thinking in how The Swatch Company flat-out decided to elevate Omega in the early 90s (the Swatch company owns most Swiss watch brands, Rolex, Omega, Longines etcetera). The increased prices of LTD guitars in the past 10 years has more to do with that they've decided LTD is a big enough brand name to warrant the prices rather than a result of increased costs etcetera.
That being said, who cares about whether it says LTD, EII or ESP on the headstock, as long as the specs and quality is there? My two LTD Elites are, identical to the first line of EII Elites (and was in essence a rebranded ESP standard, assembled on the same manufacturing line, by the same people, with almost identical specs). The only difference between LTD Elite and EII was literally the name on the headstock and +-15% on the price.
