I don’t think you can apply a consumption tax large enough to meet our revenue needs without making it impossible for people in lowere income brackets to survive.
That is the point of consumption-based taxation: it should hurt everybody when the feds spend money!
Your misguided tendency to subjectively favor one group (lower income earner in this case) over any other group is what has gotten us into this horrible mess of debt.
The efforts of otherwise decent folk such as yourself to shelter millions of voters from the pain of spending is why we have so fricking much spending.
What makes matters worse is that increasing amounts of money are stolen from Peter in order to pay Paul for doing nothing. Which means those voters not only don’t have a reason to care about cutting spending, they now have a great interest in keeping it high and growing.
