1. Then that $1 billion would be revenue, not "overall income". Overall income would be deducting other expenses (such as dividends) from that $500 million.
2. Not necessarily, but then again not every business is a big corporation that can do that sort of thing. Small businesses exist too, and they're the ones that benefit most from these tax cuts.
3. Or they could be a centrist, right-leaning centrist, a left-leaning centrist or liberal disaffected with the Democrats, etc. Just ask
@Adamska or
@Alec Benson Leary.
This "left-wing Trump opponent vs right-wing Trump supporter" dichotomy you're currently pushing is a completely false one, and the fact that you're pushing it at all is likely a sign that you live in a bubble.
4. How? What mathematical reason (which you still haven't given) is there for higher taxes being able meaningfully "bring debt down"? You still haven't given the scope that these higher taxes should have (who and what they should apply to)? What should be the percentage range? Hell, you seem to be deliberately evasive on this in general, although it looks like you just want higher taxes in some nebulously "high enough" and "wide enough" form to "bring down the debt".
Even if we didn't just tax, but just took
all of the supposed approximately
$1.9 trillion that the big megacorps collectively have, and applied
all of that to "bringing the debt down", we would still have around $22.1 trillion dollars in debt.
