What sort of stimulus can they even realistically pursue? Consumption is difficult as hell to drive in an economy that has effectively turned significant portions of its domestic workforce into a second class with the migrant worker and municipal registry crap, those people will attempt to invest it to get out of their second class status, they're not gonna start buying temu crap en mass. Pumping money into the consumer side will just hit the already fucked property market, or outflow as people try to buy property domestically or abroad. Pumping it into the producer side won't help because there's not a lower effective cost of product they can subsidize that'll restore demand, more attempted outflow will only increase tariffs. And pumping those goods into the domestic market is what's fucking them in the first place.
This is a genuine question, because I've not seen a situation like this before and I'm not sure what they can do about it.
