To fall with the door into the house: The publicized design of a "Mietendeckels" for Berlin apartments is a force! Perhaps the most real, most genuine and most powerful force in decades. Because he has found a simple and above all left answer to an easy-to-describe problem - too high rents and at the same time too little living space, namely: Rent down.

Rental cover is of course a very ambiguous term, because it sounds as if you keep a lid on the contractually agreed sum and preserve the price with it. In fact, it is also about subsequent rent reductions in existing tenancies. The classical counter-argumentation is always suggestions for state regulation market damage, loss of investor confidence, discrimination of private owners, and so on. Also interesting, right? How the rules of the market were so well inhaled that they can be reflexively reclaimed. Just because something is common, which now understands only as a footnote, it is far from ethical.

When home ownership is sold and rental property giants take over the houses, you can not open letters as fast as the rent increases flutter into the house. An Unemployment Benefit 2 beneficiary may already force an increase of a few euros to leave the apartment because the cost of accommodation provided by the Job Center has been exceeded. However, the accommodation costs are, measured by the rapidly rising rent levels in cities such as Berlin, sogrotesk low, that you better right on a tree pulls.

Especially in a district like Kreuzberg, which was a really lousy mess without proper infrastructure before the settlement in the seventies, the situation is unfair. It was the guest workers who, together with leftists, students and squatters along the former wall, made the area what it is today: an investor's paradise. The migrants, the Greens, the left and the ecos have their shops, tailors, their clubs and bars, theirs alternative kindergartens and schools and everything that they knew from Guatemala or Greece, Göttingen or Gaziantep or what they always dreamed of. This is the same everywhere in the world: The workers and Secondos make from wasteland (Kreuzberg incidentally, so was the official plans, should be city highway) livable village centers of major cities. Then the investors come in, lift each manhole cover, install a walk-in shower with slate floor tiles, planting garbage with ivy and rent or sell the Gulliloch as upscale living space for barren people with barren views, but a little more rattle in the wallet. The original inhabitants just have to move and that's how it happens. The Kreuzbergers move to Reinickendorf, the Reinickendorfers move on to Marzahn, the Marzahns move to Brandenburg, and those who can not afford it (they are getting more and more), then they roam, well, they do not know, Jupiter, Mercury or Saturn.

That's why the leftists in Berlin have suggested that existing rents - some more, others less - get cheaper again. So it's no longer just about the rumgeschraube to existing laws as the legendary Mietpreisbremse, which hardly any tenant has understood anyway. Or have you ever met someone in your life who asked "How are you?" answered, "God protect the rental price brake, it has saved my life!"
