just like any other ideaoligy. does democracy work perfectly? no. its the least bad one for now.
lets make it easier -
communisem - 'everyone is equal'. someone have to lead and make Decisions. people who get to the position of being elected to be the Decisions maker have strong will and Great ambitions. so they claim the power of the job.
and, remmember, all the communist countries look like that because USA is blockading them and banning them. people fled to russia teritories in the beginning of hte cold war you know. and cuba is waht its now today because the revolutenist didnt liked teh USAiands buiesness mans who, litealry, bought slaves in there. so after they kicked out all the Corrupt and strong people, who just took cuba to themselve, they wanted to make cuba be for all of its citizens, what usa dont like either. they like when a buisness man do whatever we want. want to mine gold with the cyanide process {google it}? thats ok! who care about what happen to the nature?! its your property.
for say, why you think you hate so much the french? because its easier to the Conservatives to hate them, because they have free medical Insurance and etc., so hating them will make them look silly, rather than let the mass ask "why dont we get free medicens when we sick?" "why my son cant get the Surgery that can save his life because of lacking in money, while my rich neigbore can?". isntead, you say "hah... french. they surrendered. lol".
and thats why, my dear, you hate the communist. cuz patriotism is hating every other nation but yourself.
