Politicians like this scheme because there's graft involved. They can get contributions from the companies that participate in this.
The so-called environmental politicians would prefer to see something scrapped than for someone to get some use out of used electronics.
I'm typing this right now on a HP laptop that was thrown out. It had HP's infamous lead free solder ball grid array problem. Taking the motherboard out, putting it in a toaster over at 350 for 10 minutes, and then blowing a heat gun on the graphics chip until it reached 200 deg C. got it reattached. I had the same problem with a HP printer.
Every LCD TV in my house has been something that I repaired. I don't strip out the boards from TVs I can't use the make a buck on eBay. I give the extra TVs I fix to friends and to non-profit organizations. But that's really against the law here.
The best thing I got was a Jura coffee maker. It just needed a valve replaced at $28 shipped from Germany. New ones sell for $1400, and used ones are at least $300. (Not that I would pay that much for a coffee maker.)
