Living in the UK, the vast majority of guitars are imports - regardless of whether they are made in the US or in Asia. I don't care where an instrument is made, I care more about the quality of the materials and the work. The issue is not so much where they are made, its the principal by which they are made. If you look at PRS for example an SE is made overseas but to hit a specific price point. If they made the SE in Indonesia with the same quality materials etc, it would probably cost as much as a CE, if not more so they have to compromise on materials too.
They are not just cheaper because labour and overheads are cheaper, they are cheaper because they are built to a price point - whether that's $500 or $1500. The difference is that the Price determines the build and quality where as with a core, the build and quality determines the price. When you can use all the very best materials and take as much time as needed to ensure everything is 'perfect', that sets the price. However, if you have a price point to meet, say $500, you are limited to what materials you can use, how much time you can spend on each instrument etc.
There is no reason that an Asian Luthier could not make Guitars from all the same quality materials, spend as much time crafting and ensuring everything is 'perfect', built with the same passion and care as any US Luthier and make it much cheaper because of lower overheads/labour costs. Companies though aren't going to these and asking them to make 'high' end guitars to compete with their own US designs, they are going over there to as for guitars built to hit certain price points under what they could make in the US. Because there is a 'price' limitation, you get 'compromises' made to hit that price point. If you are making compromises, then its not as 'good'. What building overseas allows though is less compromise because the labour and overheads are less - you are likely to get better quality for $500 if made in China for example than in the US.
An SE is great value for money because its made overseas to a price point. They certainly punch above their price point compared to a US made Core PRS for example - we all know they are not a quarter of the guitar despite being a quarter of the price. That difference though is going to be something that the individual will have to assess if its worth it or not. That can vary from person to person, what disposable income they have to spend on a guitar, what that guitar offers and how much you may want/need its features etc.
For example, If a Custom 24 is your main instrument, you may feel its worth spending more to get the core version but then you have 1 song you do that needs a 7 or 12 String or a Floyd Rose. For what you want/need, spending $4k+ on it doesn't make sense so looking for a cheap import equivalent is logical - nothing is stopping you from upgrading later. If you only have $1k to spend, then maybe an Import is a better buy, less compromises than a $1k US made guitar may have.
Regardless, everyone is different. I can't say I would never buy a 'Made in China' guitar because if it was the 'right' guitar for me at that point for whatever reason, where its made is irrelevant. I wouldn't spend 'Core' money on a 12 string or a 7+ string instrument right now - even if I have the money to do so. I would look to an Asian import because I don't play anything needing more than 6strings enough to justify that cost. However, if I won the lottery, then I probably wouldn't buy an import. My opinion would change because the circumstances are different. Therefore, I don't have a 'fixed' opinion, its very much dependent on the situation at the time. The last thing I ever look at is 'where' the instrument is assembled...
