Many ( but not always ) times that is very true.

One thing I've noted is that as the plane SIZE increases the build quality and included hardware quality also tends to increase, non-proportional to the price of the plane.
This holds true for both name brand and the knockoffs.

Of course there are always exceptions, and vendors that skew things...

e.g. my Composite-Arf's are very well built planes with decent manuals, but a novice would be thrown by the amount of hardware they must provide to finish the plane, let alone the amount of "finishing" they must be involved in. Of course by the time you are flying composites, you better NOT be dealing with crashes!
