I think it is a question of what do you consider as being rich? More than 16 million people in the UK have savings of less than £100 from a study by the Money Advice Service (MAS). They would obviously struggle. When millions are worrying about where their next meal is coming from, anybody who dabbles collecting Star Wars is probably ok.
That being said, as I have stated before, if you go back 15 years ago, or even 5, you could pick up Star Wars significantly cheaper than now. Vintage Star wars has got caught up in a sort of bubble, like a boom and bust, but now Disney have picked up the franchise I think the ship has past of cheap vintage star wars toys.
