Katharine, because the luxury end of the market pushes design and technology.

Motorcar racing is pure luxury and fun for those spending billions on it, but this is how we got disc brakes (Jaguar), fuel injection (Aston Martin, I think), safety belts, airbags, etc.

Also, items introduced as luxuries become commonplace: laptops, smartphones, washers/dryers, microwaves, central air, overseas travel, second cars, etc.

Best to you for 2023!
