Of course, those prices will creep up eventually, once the causal link between the consolidation and the market power has been sufficiently obscured. Look at "inflation" - every business was able to blame "supply chain issues" (that they caused by removing redundancies) during COVID to extract unthinkable price increases out of the public. Because every business has only two or three real competitors, all of whom have extreme levels of class discipline and will agree to lie their asses off to the public.
This level of consolidation was allowed because your politicians stabbed you in the back in the name of the """free""" market.
