The mixed government we currently have - (un)like that of the Founders: an executive of kingly nature that will gladly give his entire kingdom to his southern neighbors, a Senate of ego driven self styled monarchs who desire fame and attention but also to remain unaccountable for their decisions or legislation, a Judiciary of colluding ideological tyrants who actually feel that they are capable of "judging" the masses, and a House of democratic nature which also excludes themselves from the legislation they write.
All of those branches above are supposed to be the 'public SERVANTS' not 'public RULERS'. Once "We the People" remember that little fact, and force these miscreants to remember it as well, life will get better. Until we are willing to play our part in this play, we get what we deserve.
Wisely though (heeding Herodotus' points above), the Founders counted much upon the jealousy of the separated- and incomplete- branches, and federalism, to keep the government in rein.
