Change occurs in direct proportion to dissatisfaction, but dissatisfaction never changes.

The aphorism links reform to felt discontent: the more acutely people experience a gap between what is and what ought to be, the more pressure there is for change. The second clause—“but dissatisfaction never changes”—adds a paradoxical, cautionary note. It suggests that dissatisfaction is a constant feature of human and social life: even when one problem is solved, new grievances or unmet desires arise, so discontent remains a recurring engine of motion rather than a condition that can be permanently cured. Read this way, the line both explains why change happens and warns against imagining that any single change will end the impulse to seek further change.
