Dogshit healthcare being decades behind that in the west

Cuba, CUBA, has higher life expectancy expectancy than the US. You're literally bullshitting, the USSR at the time had the highest number of doctors per capita on earth.

Education was dogshit lacking the basic necessities

That's why they went from being starved peasants to putting the first person in space in the span of 20 years? Again making shit up

Most jobs were completely unnecessary. They provided nothing of value.

Funnily enough, most jobs were much more necessary than jobs in capitalism. No financial sector bullshit, instead focus on heavy industry, agriculture, infrastructure and development. You can make criticisms such as some factories being outdated (due to respect for the workers employed in them and not wanting to fire them as in capitalism), but it's laughable to me that you'd believe socialist countries had less valuable jobs than 50% of the population working excel tables as we have nowadays lmfao

Rationed. Not subsidized

Both. You specifically needed to ration because inequality being extremely low and prices being subsidized, it was the mechanism to ensure distribution of goods. Nowadays, the mechanism to distribute goods is actual poverty, as in poor people cannot afford it. On average, people don't have more meat, don't have more bread, it's just that rich people enjoy it and poor people get fucked. Rationing was a fair distribution mechanism that ensured everyone had a portion, and much fairer than the contemporary alternative of "the poorest 50% consistently get fucked". The top 10% richest Americans consume 50% of the goods and services. How's that distribution going for the rest, who can't afford a house, a car, or furniture?

and it wasn't a good car

"Gommunism is when cheap car". To further elaborate, yes, technology was less developed in the countries that started industrializing in the 1940s than in those which industrialized since the 1800s using the raw materials and slave labor plundered from the global South. The thing with cars and why you cherry-pick them is that they weren't a priority. Cars are an inefficient mode of transportation and public transit was prioritized. Cars are actually bad and communists have always known this, that polluting and congesting your city with 1-ton murder machines is bad, so they focused on trains, trams and trolleybuses, all much more sustainable, efficient and clean. We could talk about airplanes if you prefer, and how the USSR developed modern aviation competing with that of the US and actually exported it at lower prices than the US could achieve because they were more efficient.

black market dollar

How's that relevant to inflation? People earned Rubles and paid in Rubles. Prices were literally dictated by policy, the exchange value of the dollar is absolutely irrelevant to the inflation inside the Soviet economy, inflation is not defined by exchange value of a currency in the black market, the definition of inflation I'd "general, sustained increase in prices". And, over the 40 years between WW2 and Perestroika, prices literally didn't increase (whereas salaries did increase many times over).
