Ignoring the obvious tone leaning toward “class warfare”, the root here is a very serious issue. Just because one has the money to pay for water doesn’t mean that one should use it wantonly. Public goods like potable water are things that we all need to survive, and conservation is the key. Find the price that pinches based on net income, impose more severe restrictions on outdoor use, and incentivise conservation technology. These are things that we can all do–poor, rich, and middle-class.
The persistent water shortage is illustrating parallel worlds in which wealthy communities guzzle water as poorer neighbors conserve by necessity.
