Dan Snyder HATES The Commanders Success
well yes and no
first to address your question to me, the conceit of capitalism is that competition fosters smart growth and development of quality goods and services
when the government winners and losers before competition even begins it's not competition
secondly, communism has never been tried in any sort of environment the theory was based on
communism has only been tried in places where the oligarchy had already created a failed state - so if you want to argue that communism has never turned a failed state into a productive one (and exclude some of china and pre-stalin Russia) then sure, you are correct
now do socialism
Even if a true Marxist anarcho-communist state were to be achieved or attempted, it would still be a one-party, authoritian somewhat rigid police state where civil liberties (freedom of press, conscience, religion) would eventually come under attack or be suspended or outlawed. Organized religion or the very concept of God itself doesn't exist in Marx's envisioned far-distant future utopia. "The opiate of the masses" was an ironic phrase meant by Marx and later socialist/communist idealogues for industrial proletarian workers to destroy, eliminate bourgeiouse, remnants of feudalism by smashing, closing or turning churches, synogagues even mosques into hospitals, hostels, or schools. If you were a believer, you'd be mocked, shunned, or discriminated against by being given menial, "go-nowhere" jobs with little socio-political, economic mobility.
Marx might've been a child of the Enlightenment and Hegelian dialectic theory, but he was no democrat or really believe in representative forms of government. He, Engels, and later more radical socialists/Communists like the post-WWI German Sparticists of Rosa Luxembourg and Karl Liepernekt, as well as Lenin, Trotsky, Zinoviev, Buhkarin didnt believe in political compromise, they were self-serving, self-righteous distant who believed if they could kill, murder, rape and torture hundreds of millions of people over several decades and it would still somehow achieve a anarcho-communist state, hey, it was all forking worth it, morality and humanity, be damned.
And you're wrong about communism being tried only in failed places and besides, typically after most civil wars and revolutions, aren't most countries internal socio-political, economic infrastructures sort of frayed or somewhat damaged? That's what typically happens in civil wars and revolutions in general in that a lot of sheet gets destroyed and a lot of people die violently. It occurs regardless of whether its a nationalist or a successful left-wing revolution like the Sandinistas in Nicaragua, or Castro's Cuba. As much as I disagree with their economic or social policies, at least Hugo Chavez and Salvador Allende were democratically elected and as so, were responsible and beholden to their constituents as such.
One of the Soviet-bloc's most innovative, sophisticated, technology advanced satellite states was in East Germany. Throughout their 41-year history, GDR actually had oldest and healthiest life spans amongst Warsaw-Bloc along with Hungary and Czechoslovakia, their workers, factories were some of best-educated, well-trained and productive by the late 60's in Eastern Europe (even better then still-fascist Spain and Portugal), holiday and workers compensation, injury insurance as well as medical care was better then the USSR. Only problem was that still didnt erase the fact that the leadership (Ulbricht, Honoeker) was corrupt, power-hungry, intensely paranoid about potential civil unrest and qualified East Germans fleeing the country ("brain drain" got so bad by the late 50's that it lead to East German authorities, with Soviet permission, to construct the Berlin Wall). GDR was also one of the most heavily spied upon surveilance states in human history where its been estimated that among a population of around 10-15 million, 1 out of /6/7 were likely a Stasi spy, unofficial informant, minder, or collaborator. And unlike the CIA and the KGB, the Stasi and the NVA used some of the most innovative, creative yet diabolical forms of domestic surveilance on supposed/potential dissidents, politicians, foreign reporters/journalists, embassy staffs. Even used attractive male Stasi "Romeo honey traps" to prey on young but vulnerable Western women working as mid-upper level positions in Western embassies, governments. The highly recommended Deutschland series, especially its 1983 2015 version shows a Stasi agent living and working undercover as a Bundswehr Lt. as an aide to a prominent West German NATO general is one such example.
The great, fearless West German Willy Brandt's career as Chancellor ended in mid-70's when it was discovered that his chief of staff and wife had been undercover Stasi agents for years. IMHO, Brandt mightve been one of Germany's best, courageous and most successful politicians post-WWII, next to Helmut Kohl. Even the Stasi admitted later on that their undercover espionage operation with Brandt went in a direction highly unfavorable to them.
