The smart ones will own their shop outright. If not, they are on a longterm lease.

Also, don't knock it, a quality vacuum like a Kirby or Miele will go decades, are incredibly quiet, and just need maintenance on wear and tear, which these repair shops provide. I think we got used to thinks being terrible. Like my Dyson, does good work, it's also very loud compared to my financially secure friend's Miele.

Tough as consumer goods are generally getting cheaper and better quality. Can’t remember the last time we had a problem with the TV. We have left them behind when moving apartments as they’re relatively cheap now
