Supply and Demand, there is not enough Demand for higher quality components that are made in the USA. You might want them, I might want them, Bob might want them, but the three of us will not keep the doors open for a company. Some of it probably comes from the age group involved with the majority of drone sales and some of it has to do with a drones life expectancy I suppose. Maybe it is not fair but I do not think you have many people right now that would consider buying something of the quality that it could be handed down to their kids when they can buy something cheaper and spend the rest at Starbucks. Hell, most people don't respect what they have regardless of its cost or quality (My opinion), so why would they spend more. Not drone specific, just a comment of the status quo.
And in general, we are not talking just double the price, often I would say double is the low end all the way up to 4-5x depending on what you are shopping for on similar items (read not the same). Look at your collection of drone parts or tools and what you have spent, could you afford to have what you have currently if everything was four times more expensive? This is the flip side to the coin of spending more on a perishable item. I will build a cheap as possible drone to try stuff with so I don't have to risk my more expensive KDE motors doing stupid things
because it hurts the wallet more to replace those KDE motors than multistar motors. I also won't use my good wrenches as a hammer in a pinch.
If you are going to shoot gaps in trees at 65 mph and likely break something this afternoon, do you want to loose 40 bucks or 120 bucks in parts?
One of my other hobbies is firearms. Here is a group that is really fighting for USA made items of a higher quality and accepting the higher price. A scope mount might be 60 bucks made in China or 200 bucks made in USA, there was a time that very few would want the 200 dollar mount but that has changed significantly in the last 5-10 years. We now have enough people demanding that $200 high quality mount that shops can stay open. As a result you have shops like Larue, TPS, and American Defense that have opened and are doing well with cult followings. But even considering how well the american made industry is doing in firearms, you still have a large portion of the group that will buy a scope mount or a hostler or a bi-pod from an over seas manufacture because they save 75%. And that same person will let you know how stupid it is that you paid four times more for your similar product even though you supported an American company doing so.
Buy once, cry once.
