The thing is we are talking about details that are quantifiable and can be measured. That's what makes a difference between something like say, a bass built by Roger Sadowsky with hand picked woods and time taken to be precisely built, compared to a pile of parts randomly grabbed out of a box and bolted together by people with zero knowledge.
There is a reason there are high and instruments and starter instruments.
A Ford Festiva is a great car and will get you to the store the same as a Mercedes sl500. But what would you rather drive?
There is a difference and those differences and details are quantifiable and can be measured.
Sound or tone is completely subjective though. And let me be clear on that. I'm not saying that one is necessarily sounds better than the other that's all left up to the person who is playing it.
But overall quality and build is not subjective.
I'm sorry but your commentary came of as very snobbish. I play an EBMM SR5 as my main bass, but have no problem picking up my squier whenever I get the chance. Is my SR5 a better built instrument? YES IS my VM V slapped together with inferior parts and workmanship? NO
