Consumer interest for starters.
Yes, and then there was a $600 limit on bank taxable interest. That went away in the 80’s under Reagan’s tax deal with Tipp O’Neill.........That would be nearly $1500 today. They should bring it back.................
The other point they never mention is the income tax started at a high marginal rate i.e. in 1963 it was 20% from zero adjusted income to $4000. I think the standard deduction was the lesser of 1000 or 10% of your AGI. I know because with an income of about $1800 I had to pay blasted income tax on a part time school job. Today, that qualifies for zero tax and a check from the government even if it the income is adjusted for inflation.
