Stuff still is repairable these days, it’s just most of us live in countries where labor is so expensive locally it makes more sense to just buy a new one than to pay someone to replace components on a circuit board.
I've fixed old electronics myself sometimes and quite often it's doable and the spare parts usually cost approximately nothing. However, paying someone 50 euros for half an hour worth of work to fix a thirty euro Christmas decoration doesn't feel like a good deal. Maybe for 10 or even 15 euros it would be.
Right? If the replacement is $500, and the repair guy is going to charge $100/hr in labor to diagnose the issue and repair it plus an unknown cost of replacement components, the risk of spending more on the repair is quite high.
