He was very nearsighted, but also very vain. There is no photo of him with glasses. So our illustrator drew him with glasses on if possible.

They did not forget greed. According to Engels, "Flat greed has been the driving soul of civilization from its first day until today, wealth and again wealth and for the third time wealth, wealth not of society but of this single ragged individual, its only decisive goal." as he wrote in The Origin of the Family, Private Property and the State.

That's a bit complicated. Marx for example wrote about unions: "Trade union cooperatives originally arose from the spontaneous attempts of workers [...] to enforce contract terms that would at least elevate them above the position of mere slaves. The immediate aim of the trade-union cooperatives was therefore confined to the requirements of the day, to means of warding off the constant encroachments of capital, in a word, to questions of wages and working hours. This activity of the trade union cooperatives is not only legitimate, it is necessary."

In so-called communist countries, the leadership usually claims that the working class is free and in possession of the means of production, so there is no need for unions and minimum wages, etc. Yet the means of production are usually owned by the state, not by society.

According to Engels and Marx, states have no say in this. A state can't decide to be a communist society in their argumentation.

I was a little afraid it would turn out that way, but no problem.

It's not so easy to say what paths to a classless society Engels envisioned, anyway. He wrote political texts for about 60 years and changed his mind from time to time. He and Marx lived in societies deeply defined by class and property. I think his path away from greed is a path of rethinking property. He had hoped and expected society to evolve.
In the End of "The Origin of the Family, Private Property and the State." he quoted the American anthropologist Lewis H. Morgan:
" The time will comenevertheless, when human intelligence will rise to the mastery over property, and define the relations of the state to the property it protects, as well as the obligations and the limits of the rights of its owners. The interests of society are paramount to individual interests, and the two must be brought into just and harmonious relations. A mere property career is not the final destiny of mankind, if progress is to be the law of the future as it has been of the past."
