The welfare state increased 3x since post war time so that one is plain wrong. It was not clear if the 2nd part was "its" or separate . What is the metric for concentration of /power/? Rather than wealth. If anything the recent developments are the result of more direct democracy. Candidates like trump would have never been allowed by concentrated media and party machines mid century
