I think that the price of manufacturers being in the market is to do public good. Government police business so can insist on behaviour. Manufacturers only allowed to market certain goods if made indefinitely repairable - simple!
Central heating boilers are explicitly designed to be effectively immortal. Every part can be replaced. Often replacement parts are of better quality and\or cheaper - new spares can use technology not available when the original device was designed. Really matters as boilers can kill. There are internationally-agreed standards for heating devices, validated procedures, recognised qualifications for training etc even though it’s still an industry not a profession.
Cars are not as good but there is a growing realisation that almost any car is repairable by locally manufacturing new parts due to the wide availability of 3D printers. Old cars are being upcycled. Many cars are actually pretty identical inside, using one of several ‘platforms’ - a VW platform for example, ‘powers’ many SEAT-branded vehicles. Open source hardware is the way to go.
As restart parties grow, maybe a future for us is to help found producers of ‘print it yourself’ open source spares centred around maker spaces. So as to help government legislate that some goods are designed with ‘print your own repair’ in mind. I think producers of throwaways are polluters. The polluter to pay through schemes that survive individual bankruptcy, so actually, the industry pays. Better to not pollute in the first place.
Industry can and should invest in innovation to make immortal goods. I reckon today’s graduates are up for the challenge. Governments can make it worthwhile to manufacturer based on repairability saving the wider society the cost of picking up the pieces.
Let’s hope an entrepreneur or two founds ‘immortal’ companies (producing immortal profits)
