But can you turn on your juicer from your phone while you're in the driveway so that it's done when you open your front door? That's worth $400 to absurdly wealthy people.
No it's not. Absurdly wealthy people have butlers and/or housekeepers to do that for them.
This is more likely aimed at moderately well-off people who buy drivel like this *because* they like to kid themselves that they're wealthy, and are most likely in serious debt as a result.
Reminds me of a BBC programme a few years back that looked at "nice" middle-class people with fairly well-paying jobs that were still up to their eyeballs in debt because they couldn't stop frittering their money away on inessential expensive nonsense. I watched this thinking "you're earning *how much* and you're still about to be declared bankrupt?!"
(Interestingly from a Slashdot point of view, IIRC at least one of the people had spent a ludicrous amount of money on stereotypical "geek" cruft, i.e. overpriced imported anime videos, related toys, etc. etc.)
