You started well, missed the point that the EU commission is extremely capitalistic, protecting "their" own market, pro-immigration TO DEPRESS WAGES (not for any other reason), using money for policy targets, pro-free-trade otherwise (ie. when it comes to anyone but themselves), and generally extremely capitalistic in the usual deceitful way ...
As for "The EEC is related to, but not the same as, the European Union" ... suuure. In the same the the CPC is not China, it's related. The EU commission IS the EEC, and controls the EU. It has overriding power on any and all decision made and controls all 3 branches of EU government (Parliament, itself, and the EU courts)
Look, I get that people generally like the EU commission. On Hacker News, because of their Google and Apple actions. In the EU, because of them forcing democracies to accept the EU border situation and the Euro (both were rejected in democratic votes, both were forced through in less-than-democratic ways). Doesn't change their nature.
Look it up. Decide. Form your own fine opinion.
