How would an isekai setting be interpreted under dialectical materialism?

cross-posted from: https://lemmy.ml/post/271810

Example isekai with the general setting I am referring to:

• Tate no Yuusha no Nariagari (Shield Hero)
• <a href='https://myanimelist.net/anime/36882/Arifureta_Shokugyou_de_Sekai_Saikyou'><abbr title='Arifureta Shokugyou de Sekai Saikyou'>Arifureta</abbr></a>
• How NOT to summon a Demon Lord
• <a href='https://myanimelist.net/anime/30831/Kono_Subarashii_Sekai_ni_Shukufuku_wo'><abbr title='Kono Subarashii Sekai ni Shukufuku wo!'>KonoSuba</abbr></a>
• <a href='https://myanimelist.net/anime/31240/Re_Zero_kara_Hajimeru_Isekai_Seikatsu'><abbr title='Re:Zero kara Hajimeru Isekai Seikatsu'>Re: Zero</abbr></a>

Any isekai setting is welcome.
