Answer: All taxpayers are better off.
Step-by-step explanation:
In 2019, 23% of the Federal budget of $4.4 trillion was spent on Social Security which provided retirement benefits for about 45 million retired people. Most of this money came from Federal Revenues which are financed by Tax collections.
If the Unions helped more people secure pension benefits so that when they retire the Federal Government would not have to spend so much taking care of them, it can be argued that the amount of taxes paid by people would be less so all taxpayers would be better off.
