Can you please explain the meaning of the last sentence in this paragraph between asterisk?

Question

-------------------------
Poor households still lack adequate access to clean water supplies and pay disproportionately more for their clean water than do middle and upper income households; poor households still suffer from basic and preventable, environmentally triggered diseases; and poorer households still bear the environmental burdens *that middle/upper income households can afford to displace from upper to lower income areas of the city* .

Answer 1

I'd say it means that people who have a higher income can afford to live in areas with good sanitation; while their effluent and rubbish gets dumped closer to the areas where poorer people live.

Answer 2

It would help if you included the entire last sentence, but the meaning is that the more affluent can afford to move out of the areas causing disease and often contribute to the conditions in the poor sections

Answer 3

It translates as liberal claptrap. Disregard.
