Why do better MC cartridges cost a fortune?


I mean $5k - $10k for a piece of what? I can understand $10k for a turntable but for a tonearm or cartridge?
They charge and we gladly pay? And you have to retip or replace it soon enough. Most of them come from Japan. They sure know how to do business, don't they?

In this day and age of $250K speakers, $50K+ preamps, amps, $35K phono stages, $300K+ turntables (as shown above), and $50K speaker cables, what is the big deal about $5-$10K phono cartridges?
In 1978 The Audio Critic tested and found the Koetsu to be the best sounding mc phono cartridge. But was appalled by its high price - $1000!!! Today I just saw an ad for an Opus 1 mc cartridge - used: $10,000 (list price $15k)!!! I am going to wait for the Marie Antoinette mc cartridge. "Let them eat cake"!!! Such are the times we live in! Trophies for the 1%!!!
