The good thing about Aldi and Lidl is that you get to choose the quality and pay premium or not. This is one of the reasons why i often shop on any of them. I'd like to have a choice to pay premium for what i feel it should be premium.
You give too much credit to advertising and brand identity if you think "fake ariel" is something inferior to "real ariel", or that "real ariel" is something hard to achieve that means quality.
At least in Europe you have a chance to choose what you want: The classical premium brands, premium Lidl brand or cheap brands.
