The European Parliament is elected every few years by citizens in all member states.
The European Commission is nominated by the European Council and and confirmed by the European Parliament.
The European Council consists of government officials from the member states where they have been chosen by national democratic processes.
It may be a little complicated, but it's all rooted in democratic processes. Please stick to the facts and keep the populistic anti-EU nationalistic propaganda to yourself.
(Every kid in the EU has been learning those basic facts in school for decades, making it surprising that this populist nonsense still catches on with so many people. I have an easier time forgivin non-EU folks, but even those should check the facts before claiming things.)
