The federal government should end income tax on persons and implement a federal sales “usage” tax on items. In addition to tariffs, this measure would allow for American households to keep more money from their paychecks while allowing the government to continue collecting taxes (if you don’t want to pay the taxes then you’re free to grow and make all of your own items for use). While it may be disliked, I would also recommend a higher tax rate on luxury items.
The downside to this is that it’s a more “hidden” tax that can be raised without too many people noticing that it is higher.
