Who is Germany?

A few years back the government launched a campaign called "You Are Germany" in the attempt to encourage people to (as it seemed) have more children but also identify more strongly with our country.
Now, less than a week before the general election, I am beginning to have serious concerns about who really is Germany.
The reason is a recent article in the Frankfurter Allgemeine Zeitung (FAZ; a major nationwide newspaper). It describes the new style most parties have used for their election manifestos: "Simple Language". As the name suggests this is a radically simplified form of German, which focuses on the active voice, short sentences and avoids metaphors and any foreign or high-brow words. It uses few nouns and many simple verbs, like "make", "do" or "be". In fact, it strongly resembles the way you'd speak to a little child and was originally formalised to help people with mental disabilities or learning deficits.
Some examples (as well as I can translate them into English):
"Cars make lots of fumes. So there should be more trains." - Social Democrats (SPD)
"Weather all over the whole world we call climate. Because of fumes it gets warmer and warmer. That makes icebergs melt. Then the seas have too much water. And there is flooding." - Green Party
Since it is now being used for election material I wonder what this should tell me. Are most voters around 10 years old or have mental disabilities or learning deficits? Has the general level of education in Germany dropped so low that the use of such simple terms is necessary for people to understand party agendas? Or do politicians think their voters are just a bunch of retards? I get the feeling it's a mixture of the latter two. I guess, that is not surprising. Leaders and philosophers throughout history have known that the general public as a whole, the masses, are stupid.
Consider Sir Max Beerbohm saying: "You cannot make a man by standing a sheep on its hind legs. But by standing a flock of sheep in that position you can make a crowd of men."
What surprises me more is that the FAZ seems to applaude this new development (unless it's very cleverly disguised sarcasm). They even seemed to chide the Liberal Party for not following this move. I for one appreciate that the Liberals obviously still assume their voters have a certain minimum intelligence.
Surely there are people with learning problems or mental disabilities in Germany. They should not be excluded from daily life. I just wonder if their mental capabilities should be taken as the new national standard. Or if somebody with drastically impaired mental capabilities could be trusted to make a mature decision and contribute to the future of our country.
And what's more is that this deliberate use of Simple Language over-simplifies potentially complex issues for the reader. It's one thing to use simple terms to explain to mentally impaired people what global warming means. To discuss possible solutions and how to implement them, and then let the impaired person make an informed choice on who to trust is an entirely different matter.
Moreover, the naïve ordinary reader may then also have the impression that the problem (and its solution) are that easy - "it gets warmer because of fumes, so let there be more trains". The thing is that these issues aren't as simple as that. It may be uncomfortable for the average citizen but that's the way it is. And to relieve people of the need to do their own thinking would mean to breed a nation of morons who get their knowledge of the world spoon-fed by the government. Another brave new world.
