It's a question asked by Newsweek in a piece that hypes up the protests and fake politics that exists in America today.
Rather than answer the Newsweek question....I would start off and ask if the Soviet Union in 1918 was ever destined for any legendary greatness?
History is an interesting piece over this era. After the revolution in 1917....the Czar fell from power fairly quick. A committee of 'idiots' came to be formed up with Bolsheviks running things up through 1922. Lenin? He was merely an ideas guy....the type to walk in and stir up trouble with great speeches. When the smoke finally cleared in 1917....there was no real plan and no real assembly of four-star leadership.
After Lenin's death in 1924....Stalin stepped in and become the sole boss. At that point, the committee idea existed in theory, but Stalin was the one allowing each to have a small piece of the pie.
In truth, there was no political party....you were a citizen or resident of the USSR, and the government was one single big cog with only one single direction. You conformed, or you found some way of exiting the country. If you desired some alternate lifestyle....you were going to end up in Siberia. Folks might say some party existed....just for meeting purposes and attending a free-food situation, but it probably didn't really qualify as a real party.
It's a false sense of reality to suggest that politics ever was offered in the Soviet Union. People may sit around today....huff on some glue, and drink some great rum-and-Coke cocktails....discussing this like some intellectual situation. But the Soviet Union was just a car running on fumes and a empty tank for seventy years.
So, you move onto the US and some fake intellectual discussion of a one-party state.
Maybe up until the 1980s....there was still a GOP situation and a Democratic situation. I think since the mid-1990s....with radio talk-shows, the internet, cable news, the demise of the print-media (in particular Time, Newsweek, WaPo, and NY Times)....you have a charged up agenda driven political system.
McCain may have an "R" behind his name.....but most people who say they are Republicans don't really value what McCain has to say and they question his behavior and ethnics.
The same is true with several Democrats.
Agenda groups, lobbyists, and special-interest foundations are mostly running the one-party state that you see today. No one respects the news media that much. The protests around universities now? They are questioned to some degree....fake protesters are bused and in and pretend to be part of this group or that group....depending on the day of the week and the pay-scale.
In the 1970s, you could have asked most folks to name their governor, their two state senators, and their district Representative....with the bulk of people (well over 70-percent) only able to provide one single name. Today, everyone is hyped up to the degree that they can name all four characters, the VP, most cabinet officers, and the bulk of the Supreme Court.
We are in a different age and a morphed culture. It's not even a real political system....just a collection of pretenders, actors, and special-interest groups shuffling around and trying make people think in some relative way that it's all a democracy. In essence? It's a great illusion act worthy of a big-contract deal in Vegas.
