It is actually quite fun to read Dostoevsky’s Idiot with that in mind that Dostoevsky might have written Prince Myshkin (the Idiot) with Leo Tolstoy in mind. Dostoevsky was very much not a man of means, whereas Tolstoy literally came from a line of nobility. To Dostoevsky, Tolstoy’s talk of the impoverished must have sounded like he had no idea what he was talking about.
That being said, I do think that romanticism of the poor is a really old school mentality, maybe some boomers sometimes still engage in it, but I doubt that you’ll find contemporary leftists engaging in it. Today’s left is much more AOC and Greta Thunberg complaining about how shitty life is for the poor (with a substantial retweet history each backing up poor people calling for it).
