I get that it's Bloomberg's duty to root for the landlords, but to me the data in the article shows a very clear win for renters.

If I'm reading the graphs right, price controls in Berlin have slashed rent price growth by nearly 60% for almost all of the city's apartment stock.

Meanwhile, rent for the remainder, those apartments built since 2014, is only growing 10% faster than the baseline.

So if we're gonna do the math: [lots of apartments * -60% inflation], against [fewer apartments * +10% inflation], equals a presumed windfall for renters, versus the alternative history where this rent control policy doesn't get enacted.
