What is the theme of time machine by HG wells

I think class struggle is a major theme. Wells capitalizes on the struggle between these two groups in his depiction of civilization 800,000 years in the future. When he first meets the Eloi, the Time Traveller initially believes society has evolved into a form of communism. However, as he learns more, he realizes that the class struggles of the nineteenth century have continued and are manifested in the relationship between the Eloi and the Morlocks.
