What type of income for retirees is not federally taxed? SS is taxed, many 401K's are taxed. Many annuities are taxed. I am not sure that article is completely correct or what he was referencing.
Roth IRAs are an example of a tax-free vehicle with yearly contributions of $6,000/year for an individual. For someone entering the workforce and looking to save for retirement, these make for a good starting point. Even for older folk, a Roth is a good choice.
As an example, If I wanted to retire in 30 years, I could save close to $600k in just my Roth, assuming 7% returns. With that being said, most use 7-9% as their rate per year, depending on their investment strategy. Pretty sure the next few decades won't be that high though.
I will say that Alaska has something similar to UBI, but the money is tied to oil. Though what ya'll are discussing is way more than what is currently going on up north, maybe by a factor of 12.
Increasing taxes on the highest earners might be one of the ways it can work**
**For those using several European nations and their tax rate of say 50%, that is the highest tax bracket and doesn't necessarily mean everyone is taxed at the level. Furthermore, if you happen to be paying 50% taxes, it does not, by any means, mean your entire income is being taxed at 50%. There are things called tax brackets. The wealthy individuals being taxed at a higher rate than regular folk like us will still be able to live lives we could ever hope to live.
A very basic example is below.
Let's assume there are two brackets, anyone above 50k/year is taxed at 50% while those below are taxed at 10%. Most would think the person making 60k/year would pay 30k in taxes and be worse off than someone making 45k. This is not the case. The person making 60k would pay 50% taxes on 10k or 60-50 equating to $5,000. They would also pay an additional 5k in taxes or 50,000*.10, for a total of $10k paid in taxes. Essentially even with their high taxes, they would still be paying less than 20% of their income in taxes.**
**This is a very rudimentary example as taxes are infinitely more complicated than the example above. The numbers used were just for ease of computation. It's those paying the highest taxes currently would just have to pay more if taxes are raised.
