Why is there no love for Prima Luna?

Perhaps the OP mistook the few available negative PrimaLuna posts as representing the population at large.  Perhaps there are a lot more satisfied owners that simply are not posting maybe because PrimaLuna is a relatively established company so much has already been written/posted about their products.    
My experience has been the opposite of the OP - most PrimaLuna reviews have been positive with most agreeing that the engineering, quality parts (not cheap), quality build (again not cheap), and point to point wiring (labor intensive- expensive) make PrimaLuna a good/great value at their price points.  
Although the China comments were a bit off topic, I did appreciate the thoughtful comments like from @jjss49.  People are people - we love our friends and families (warlike Klingons aren’t real), work hard to survive or get ahead, and are less than satisfied with our governmental performance....or lack thereof...  

I disagree that it’s US greed, rather, it’s the nature of living in a capitalist society in which businesses are encouraged to compete to drive down prices.  Generally speaking, businesses are driven to maximize revenue while minimizing costs.  Labor costs are usually one if not the largest expense in manufacturing.  We live in a world economy.  If we kept labor in the US, the significantly higher labor costs would have to be passed on to the consumer meaning higher prices.  These higher prices would significantly negatively affect sales both here and abroad due to lower price competitive products.  The reduced sales is opposite of the typical business who goal is to increase sales/profits.  We all want lower priced quality products, but this is heavily dependent on controlling manufacturing costs.
