> So what was recently a £20 simple repair to your fridge or cooker is now a £200 major component and more labour than it's probably worth.
I think this is a large part of the problem. Our goods have become so cheap to produce that they're cheaper to buy new than to repair. For example, I'm rebuilding a small motorcycle engine for a Honda. I can rebuild the engine, paying the machine-work labor cost and a small amount of parts, and it's actually just a bit more expensive than to buy a brand-new Chinese clone that's been in production for over a decade.
Labour costs for repairs have gone up, while consumer goods have gotten cheaper. In a lot of cases it's simply more cost-effective to replace than to rebuild. No mechanic rebuilds water pumps in the shop anymore than a home appliance tech would fix a coffee maker.
DIY is largely the one holdout for repairs, and it's unreasonable to think that every person can have the aptitude to fix any device that may break in their lives.
