I once repaired my dishwasher. It cost me about £50 for a new pump, and many hours working out how to take the dishwasher apart and put it back together again. If I treated this as work, I would have been better off buying a new dishwasher, because I would have been paid more for those hours than the cost of a new dishwasher minus a pump.
Appliances are cheap relative to wages now, and repair still takes a lot of time. That’s the simple answer.
We have to consider why we want to encourage repair: it’s not simply true that we should always prefer to repair for its own sake. We should true to minimise greenhouse gas emissions or the use of resources that can’t be reclaimed, but not to the exclusion of all else.
If we had a carbon tax for example, it would somewhat increase the price of new goods and promote repair. But such a tax would not cause people to repair everything reparable - there would still be reparable items that are not economical to repair. This is a good thing though - if the carbon tax correctly embodies the externalities of producing emissions, then the choice to not repair it is a choice to do something else with people’s time. That time could be used on other productive things - maybe working to replace dirty fossil fuel infrastructure, or working to feed or entertain people, which are all things we want.
A plurality of the catalogued items in the museum are from Britain itself (680,000 out of 2.2 million or so) and there are as many such objects on display as there are from Asia.
Despite the memes, most of the objects in the museum that do not come from Britain were bought, not stolen, though there are some important and high profile exceptions.
