Without capitalism the increase in cost would be smaller for sure, but depending on the item it would be still meaningful. For example, the dining table from the article still needs a hydraulic system to go up and down, that isn't exactly cheap.

Instead I feel like the biggest harm of capitalism is shoving the tech even where it doesn't make sense to have it, and then telling people they need it. You don't need a smart toilet when a simple button does the trick.
