Just to be clear, let’s look at some equivalencies where the spouse receiving SS dies using this calculator from the SSA See how your pension may affect your benefits | SSA
Case 1: Higher paid spouse gets $3000/month from SS, lower paid spouse gets $1500/month from SS vs. higher paid spouse gets $3000/month from SS, lower paid spouse gets $1500/month from government pension. Higher paid spouse dies.
SS only couple - survivor collects $3000/month (66.7% of the prior combined amount)
Mixed benefit couple - the SS benefit is reduced by $1000/month to $2000, but the survivor is also still getting the pension of $1500, so collecting $3500/month (77.8% of the prior combined amount)
Case 2: Both spouses get $3000/month from SS vs. one spouse gets $3000/month from SS, other spouse gets $3000/month from government pension. A spouse receiving SS in each couple dies
SS only couple - survivor collects $3000/month (50% of prior combined amount)
Mixed benefit couple - the SS benefit is reduced by $2000/month to $1000, but the survivor is also still getting the pension of $3000, so collecting $4000/month (66.7% of prior combined amount)
Case 3: Higher paid spouse gets $3000/month from SS, lower paid spouse gets $2000/month from SS vs. higher paid spouse gets $3000/month from SS, lower paid spouse gets $2000/month from government pension. Higher paid spouse dies.
SS only couple - survivor collects $3000/month (60% of the prior combined amount)
Mixed benefit couple - the SS benefit is reduced by $1333.33/month to $1666.67, but the survivor is also still getting the pension of $2000, so collecting $3666.67/month (73.3% of the prior combined amount)
Case 4: Higher paid spouse gets $3000/month from SS, lower paid spouse gets $1500/month from SS vs. higher paid spouse gets $3000/month from government pension, lower paid spouse gets $1500/month from SS. Lower paid spouse dies
SS only couple - survivor collects $3000/month (66.7% of the prior combined amount)
Mixed benefit couple - the SS benefit would be reduced by $2000/month, but since the SS benefit of $1500 is lower than $2000, the SS benefit is just reduced to $0. The survivor continues to collect the government pension of $3000/month (66.7% or the prior combined amount)
Case 5: Higher paid spouse gets $3000/month from SS, lower paid spouse gets $2000/month from SS vs. higher paid spouse gets $3000/month from government pension, lower paid spouse gets $2000/month from SS. Lower paid spouse dies.
SS only couple - survivor collects $3000/month (60% of the prior combined amount)
Mixed benefit couple - the SS benefit is again reduced by $2000/month, which is equal to the SS benefit, so again, the survivor collects no SS. The survivor continues to collect the government pension of $3000/month (60% or the prior combined amount)
So, when the spouse collecting the government pension is getting a benefit that’s the same or lower than the spouse receiving SS, they will come out ahead of a couple receiving the same benefit amounts, but both from SS. When the spouse collecting the government pension is getting the higher benefit, they end up equal to a couple receiving only SS.
Not sure why you think this is unfair to the mixed benefit couple, since they never end up worse than a couple receiving the same amounts from just SS, and in several cases, end up better.
