Her discretionary income, despite the pay raise, will only dwindle if her health care costs remain fixed. But the whole point of moving to a single-payer system (or at least more government-provided coverage) is that those costs go down. If they go down by more than the 25% (or whatever) that Sally is losing, everybody wins: she makes more take-home pay, her company makes more profit, and health care costs less for everyone. There's a lot of assumptions built into that outcome, but I take it that's the idea, if the numbers work out.
