Vast majority of working people have federal taxes automatically deducted from their checks before they even see a dime. Most people get refunds at the end of the year instead of having to pay, so it would be up to the self-employed and basically anyone who doesn’t file a simple form to start withholding their taxes.

I guess we could talk about getting everyone to adjust their paycheck withholdings but most people live under the assumption that “everything will blow over by next year” whatever the circumstances.
