On top of that tax you STILL have to pay for your own health insurance

You didn't have to have it before, now you are forced to buy it. You didn't HAVE to buy it before unless you wanted it.

And related, a higher sales tax hurts the poor far more than income tax. Income tax however affects the rich far more than sales tax.

That's because you're not aware of how the plan works. You should study it more.

You understand this system is about how the government collects revenues, not some grand social experiment to satisfy wealth envy with Marxian theory.

Moving on, it doesn't make higher taxes. It gets rid or your payroll and income taxes. Look at your paycheck and see how much disappears. That tax is essentially moved to a consumption tax instead. The tax is simply moved to a new place to collect it. You receive 100% of your paycheck.

You also receive a prebate from the government for the tax you would have paid on basic necessities, so everyone starts on a baseline of zero tax rate (which doesn't mean much, because no one is individually taxed).

Depending on how you spend, more tax is collected inclusively on the items purchased. This isn't about taxing individual people anymore, its about collecting taxes via goods and services being transacted. The more brand new items you buy, the more tax is being collected. Tax isn't collected on used items, only new items.

If you spend like a poor person, you are contributing less to tax revenues because you're buying less things. If you buy millions of dollars of things, you're paying far more into the tax system.

Your issues with A, B, and C have nothing to do with tax revenues. This has to do with corporate subsidies, wages, and health care. This has nothing to do with taxation.

D gets rid of loopholes with this system because there isn't any loopholes. The provider of goods and services have to collect that tax (much like sales tax today) and remit it to the government. That's it. You file no tax return, you buy a $40 item for $40 where some of that is the inclusive tax. There's no secret deductions for rich people since there's no tax returns to screw around and do tricky accounting with.
