The Parliament is just a rubber stamp. One has to ask what the use of a parliament is if they have no power whatsoever to write laws.
Interestingly enough, the Parliament was also unelected until 1979. But then again, in the USSR the Supreme Soviet was elected, as is the National People’s Congress in today’s Red China. All that happened in 1979 with “Europarl” is the adoption of Leninistic “democratic centralism”. The notion of multi-party representation is nullified once you have a Politburo such as the Commission, who pushes just one political doctrine and one only.
It does seem like a hopeless design built for corruption.
