Orwell does not seem to like women very much. In Burmese Days he inadvertantly makes the claim that all women, both colonial and colonizer class, are the same, and that women have to prostitute themselves in order to attain some worth in the eyes of the male colonizer, where prostitution involves the act of selling oneself to the male colonizer, physically or otherwise.
The white woman constantly needs to assert herself in looking for a white colonizer class husband, especially while overseas. Elizabeth embodies this in her quest to marry a man who can to make her a burra memasahib. While she seems flighty and rather shallow for jumping from white man to white man, she is merely doing what women of her race are expected to do in order to keep their self worth.
For the native woman, she is told from birth that to be a concubine of a white man is far better off than anything else she could become. The male colonizers are even encouraged to keep or even marry native women, as they are less expensive to maintain than a female member of the colonizing country. Ma Hla May can hardly be blamed for trying to win back Flory from Elizabeth, as it has been impressed upon her all her life that to service a white colonizer accords her a status that makes her life worth living.
This implies that the one of the only forms of power that women have over men has to do with sexuality and sex. It also means that a woman’s worth is measured by whether or not she has managed to attract a male from the colonizer class. As a result, women have to prostitute themselves if they wish to attain some sort of power in a world ruled by white males.
