Let me clear this up for you ...
I'm already clear how confused you are ... Jesus preached a monarchy ... how does this stack up? ... viscounts sitting together sipping tea while watching their two armies annihilate each other for entertainment (and a good way to rid themselves of all their extra serfs) ... the death sentence for being one day late with rent ... farmers delivering their entire crops and then starving to death ... way to go PoliticalChic, episcopalian courts were perfect justice ...
Slavery, serfdom, or death was the way things used to be ... we're trying to move past that ... the Italians voted for the Fascists, the Germans voted for the Nazis ... you demand they shouldn't? ... then it is YOU who are totalitarian ... it is YOU who think to tell the voters of California what to do ... you don't like the liberal politics where you live?, then fucking move to Alabama ... bear all you unwanted children and let them suffer in some sorry-ass excuse of an orphanage ... then bitch about the taxes you pay to feed your abandoned children ... I understand, only the girls have to drop out of high school if they get pregnant, why should we waste tax-payer money educating girls? ... God forbid we make the boys pay child support ...
You seem a person of no power in Real Life ... you come on the internet and gain a little power and wield it like a novice ... someday you'll turn 65-years-old, and you'll be thankful for that $2,000 check every month of SOCIALIZED MONEY ... hypocrite ...
You are correct that Jesus preached a monarchy, and monarchy is what will rule when the messiah comes back.
Reading the bible one understands the time of Salomon, a king who acquired richness for "the government". When he died, the rest of the heads of the tribes came and ask Salomon's son to relief the taxes because they paid too much taxes and had no voice in the government (taxation without representation) and the answer given by the new king was adding more taxes. This is what caused the division of the kingdom of Israel into two smaller kingdoms.
The monarchies in history have been capitalists, the feudalism- which grew together with the king- decided to have their cut from power and created the Senate in Rome, centuries later the Magna Carta in England to protect the church and give judicial privileges to the barons and pay less taxes to the crown, and so forth.
Socialism is an important part in the democratic government in order to protect working populations, you just mentioned with the retirement check, plus all the social services for low income people, handicap and more.
In times of Jesus, for a survival of the widow, the orphan, the handicap, the only way was by charity from others, the kings never created programs for them. The kingdoms were to accumulate wealth to establish a dynasty, to pay the army, etc.
In modern times. only nations from Europe like the US, have a socialist system which provide benefits for the needed. If you go to South America, these kind of programs do not exist, and the rate of criminality is high, and robberies is the most common. You are washing your car, and you enter to your house to pick up the wax. you come out to the street, and somebody already took your bucket, the soap container, the rugs, if you take a while the water hose will also vanish, you have no idea how bad is for poor people to survive that stealing is the only way to make some money for food.
Then, capitalism system in the US and countries from Europe is in appearance similar to the capitalism in third world countries, but this is only an illusion. Even when, yes, there is a retirement plan like Social Security, in those countries you are fired and 35 years old, and chances to be hired again are very low. This is why in the past the population in those countries was very attracted to the socialist and communist style of government.
Take Cuba as an example, The people over there had no color TV, and neither lots of technology in their homes, but they had the best health care insurance, thousands times better than Obamacare and FREE. In the 80's people just asked to the city town center for construction materials and these were given for free so they can build their own house. A complete different system of government.
In reality the capitalist, socialist, and even communist systems can't survive alone, somehow they participate in conjunction with the main economical system of the country.
And something very interesting: Before WWII, Germany with Hitler in power, made the best economical trades with several countries of the world, were the payments made by the Germans for raw material were the most generous. Later came England and with threats of boycott against those other countries, caused the end of those economical transactions. This calls for recognition that Hitlers economical system was very good when England did their best to stop it. And this happened before the war.
The countries have adopted the different systems available to meet the worldwide economy, and if Jesus comes one day, according to the bible will be the imposition of the monarchy again. The world will become more "socialist" due to a change in the world. Right before the return of Jesus the entire world will suffer of severe catastrophes. The dollars in your pockets won't have any value.
