A quick Google search says Indonesia has around 3 million permanent homeless people vs about 500k in the US. 40 million people in Indonesia don’t have access to clean water. Half the population doesn’t even have access to sewer systems for waste.
Water is an issue. But then it is an issue in much of the US too (Flint for example).
My understanding is that the Flint situation is due to mismanagement, which was done after a certain political party created laws to remove elected leadership from indebted municipalities (most of the indebted municipalities were controlled by the opposing party).
Which is to say that the Flint situation got a lot of press because it was rare, and that the motivations were likely political rather than racial. As such, in isolation it is not good evidence for your arguement. It would be appreciated if you could provide some statistcs.
