[quote=SK in CV]A 90% tax rate is too high. I’m pretty sure nobody is advocating that today. Nor even a 50% marginal rate. Though there would be some benefits to it.[/quote]
Yes, 90% tax is too high, I agree with you there. But you did advocate for 50-60% marginal rate a few post back. You did say higher top tax rates encourage businesses to spend money, so it sounded like you were advocating for 50-60% marginal tax rate. I’m quoting what you said below… Maybe I’m just reading it wrong and you can clarify.
[quote=SK in CV]But I could make a pretty strong argument that increasing the top tax rate, particuarly on businesses, would be good for the economy, but not to 90%. Somewhere between 50 and 60% would help. Higher top tax rates encourage businesses to spend money when the government pays for half of it.[/quote]

[quote=SK in CV]And the current tax schedule looks exactly the same, just with a lot fewer and different rates. Tax doesn’t begin at the first dollar of income now, and it didn’t then. The tax rate schedule applies to taxable income.[/quote]
You’re right, it didn’t begin at the first dollar of income, but it was pretty close. Back then, there were variable standard deduction and it was 10% of your AGI. So, something making $1k/year can deduct $100, but the other $1900 was taxed at 20%. So, if higher taxes was the reason for pretty good economic growth in the early 60s, then why not advocate for higher taxes all the way on down, since back then, EVERYONE was paying taxes and we had good economic growth.
