Our discussion got out of thread subject, but let fellow
BFreaky take a coffee break.
Renze, I saw from the beginning you're from Holland.
You say Westerners laugh at Russians... But from inside of the USSR there was nothing fun.
Starting from 1945 (if about my country) all was nationalized, like they say. But in fact people were simply robed. These who resisted were tortured, killed or sent to Siberia to build military objects - we've lost hundreds of thousands most advanced citizens of a nation. We had no privacy, KGB controlled EVERYTHING - you never know whether your friend is an agent or not, people were afraid to speak, had nothing to eat - empty shops. We were simply transformed into slaves.
Today's example - North Korea is exactly the same what it was the USSR.
So these slaves had been working for totalitarian military system - machine building industry, food production, textile industry, road building, military factories’ building, power plants’ building ... up to, as you say, space technology development, which originally also has the military aim first. Saying slaves I mean cheap labour.
The technological ideas were simply stolen from the West, especially from the USA by the KGB spies. Many products were copied, modified and/or somehow developed. As to what I know, USA were developing its space technologies gently, with no hurry, taking into account safety first. USSR had just one goal – to overtake the USA whatever it costs. Have you heard that many professionals died in the accidents of rocket sites and ranges? They hide it, but there are hundreds of deaths.
Lada - Fiat-124? Such an industrial country! Why couldn't it build its own car factory if it’s so smart? So here come the licenses. Including KamAZ - not only the vehicle project, but the whole factory had been built under license. All the other automotive factories had been brought from Germany right after the WW2 (AZLK/Opel for instance).
T-150 as well as K-700 both are military tractors. Each product (except directly military) designed to have two purposes - military and civil. BTW both tractors are not well treated because of endless repairs and safety. There are several cases just in my country, when a K-700 drivers accidently died after rollover.
Financing – from trade of weapon, mineral, oil, gas. All the 3rd world is armed by soviet weapons. That money goes to ... where do you think? Yes, to the creation of new weapons (tanks, trucks, missiles, war ships e.c.), military R&D as you said. Here comes the politics. To keep up the weapon trade on top, requires to create hot spots on the Globe. Here we have wars, which are real money makers for the weapon producers. They say they export peoples revolution to the world. Would you like to import such revolution to Holland?

I don’t think so if you would see how it goes in the East.
Normally budget is a flexible thing. You can increase it for space and military purpose, but in case of economical crisis or social issues, it should be reduced or reconciled to the new priorities. That is clear in the Western countries. But the generals of so much centralized country like USSR was, didn't want to understand it. They ask for more and more, and they don't care, that people soon will start fighting for survival because of hunger danger. The world's oil price drops and country quickly goes out of budget. What to do? Already nothing, it's a bankruptcy and collapse of a country. Here comes the end.
How could a super-centralized country persist without people’s private motivation, spending most of the budget for the military purposes? No way. That system (Lenin’s system) doomed to failure from its first steps. As you know it has happened within one night only - on the 8th of December, 1991. Can you figure out any other normal country disappearance from the world map within one night? I can’t.
Sorry for so long write up, but I just described what was going on in the USSR and what were the circumstances concerning the technologies and development.
