Absolutely not when replacing costs 100% and repairing usually costs 0.1%.

And the reason people want to leave certain countries is for totally different reasons than not wanting to repair something. In fact, I would say with quite some certainty that emigrees who repaired first before leaving would still do it after emigrating.

The real reasons, in my opinion, are: 1) it takes skill and will to repair something yourself, 2) something new generally feels better than repaired/used, 3) logistics make replacing/repairing less cost efficient, 4) with every replace, companies have a new touchpoint to try to upsell their customers, 5) it takes less time to go to a shop and replace than repair, 6) it takes some giving a shit about the environment to prefer the more complicated route. And probably more.

If repairing usually cost 0.1% then everyone would do it.

The reason almost nobody in first-world countries is getting their microwave repaired is because it often costs more than buying a new one. This is because the new unit is manufactured overseas in a place with cheap labor, but the existing unit has to be repaired locally with expensive labor.

Of course people aren't emigrating because they don't want to repair things. But they are often emigrating because they want to live in a place with high labor costs (i.e. high salaries), or for other reasons that are very strongly correlated with high labor costs.
