"Electronics were much too freaking expensive for our parents & grandparents to let us get off with a mild scolding for destroying them..."
They still are. And usually more expensive to repair, even if they can be. Whole board or panel swaps in most cases. It's rare for a repair shop to do component level repairs these days. AFAIK, the stuff we deal with gets sent back to the manufacture in China, Taiwan, Thailand, wherever and we get repair or replace boards back. Labour is obviously cheaper there, it's just not economic in most developed countries where workshop time costs £100+ per hour and the board is worth sub-£100.
