Who affords First Class?

Just a general question I don’t understand…..I’ve flown from LAX to Australia numerous times now over a few years. Economy tickets usually range from $900 to $1500 round trip. But when I look at First/Polaris they are $10,000+!!!

I’m curious if people actually afford and buy this on a regular basis. Or are they usually just upgrades from miles/points etc?

I’m in the military so low paychecks. If people do buy this, what do they do for a living?
