This can be still seen today where newer manufacturers like Sukhoi just cannot get to the level of parts and knowledge availability that the US understands. Embraer is one of the few new names to break through this, in no small part down to experienced US personnel being involved.
UK designs of the era seem to be conceptually advanced, too small for the job (both airframe and engine), good airframe design, but poorer systems, especially electrics, and double especially if they were from Smiths.
