The boomers voted themselves tax cuts. TGG paid Roosevelt era marginal income tax rates above 50%.
Very few of TGG paid the 50% rate. The average income tax paid as a percent of income has been relative stable.
The SS tax rate increased from 1% to 3.625% by 1965 with maximum income being taxed started out at $1,000 increasing to $4,800 by 1965. These rates didn’t support the benefits they earned.
If you compare the benefits to taxes paid, TGG received multiples of what they paid in while most boomers won’t see just a return of contributions.
The millennials will receive a fraction of what thet contributed.
