I'm mocking anyone who is dumb enough to pay $2.5K-$3.5K for a 1 year .rich domain registration or $500-$900 for a .luxury name.
As far as .com/.net pricing, the current pricing is much lower than the $50 yearly that Network Solutions charged from 1995-1997 (and it only offered 2 year registrations) , and the $35 yearly it lowered the price to in 1997 (after it was sued) when it was the only domain registrar.
[Verisign acquired Network Solutions in 2000, so almost 20 years of price fixing by the company since the government put it in charge of .com/.net....FYI, com/.net/.org registrations were free up until NetSol starting charging for them in '95]
