I believe that all the airlines you mention
Germany -> Lufthansa
France -> Air France
England -> British Airways
Spain -> Iberia
Argentina -> Aerolineas Argentinas
Russia -> Aeroflot
Poland -> LOT
Italy -> Alitalia
are or were owned by the government of the country involved (admittedly even Air Canada was government-owned). At least three of them - BA, AF and LH have been heavily criticized for using their monopoly power to crush competition.
