So do Democrats plan to just keep raising taxes until they take 100% if the income of the anyone who is a producer?
Yes and at that rate the producers will no longer produce.
Certainly not! Because they are for fairness and equality they will not "just" keep raising taxes. They will certainly start tapping into the savings and investments of those unfair producers who stole that wealth from the people they employed and who willingly bought their services.

There is an infinity of numbers higher than 100, so they’ll keep going. You’ll just be billed for the difference.
