Well, sales tax is regressive, because a $100 shop for someone earning $20,000 is a far bigger pecentage of their income than for someone earning $200,000 or $2,000,000, therefore it taxes the poor more than it taxes the rich.
The logistics of the idea of 'progressive' sales tax make it practicably impossible, hence the need for progressive income and property taxes.
Let's cover Income Tax first:
An idividual with 3 kids making 25K a year pays $0.00 in Federal Income Tax, actually, they receive 100% back that they paid into it plus additional credits for having kids and working. This is basic Reaganomics & the Trickle down theory. It's why every Feb. we have a boost to the economy as the poor get their EIC and go blow it on big screens and x-boxes.
Individuals how make $200,000.00 or $2,000,000.00 a year do not receive 100% of their paid Federal Income Tax back, in fact, they actually pay up to 25% of their taxable income into Federal Taxes and qualify for No EIC. I would say this is a progressive income tax.
Next up, Property Tax. Property taxes are based upon the value of your home. You want cheaper property taxes, then move to a house that has a lower value, it's that simple. Someone in $30K house pays less in Property Taxes than someone who lives in a $100K house. Now, the individual in the $100K house more than likely makes more than the individual in the $30K house, which is why they can afford the more expensive home and are thus paying higher taxes. This is called a Progressive Tax.
Now, if the tax rate is 1% of the Property value for all, then how are the poor being taxed more?
If your house is worth $30k then you will pay $300 in taxes. If your house is worth $300k then you will pay $1,000.00 in taxes. See how that works?
Are you now going to arguing that 1% of a poor person's income is greater in comparison than 1% of a rich person's income?
Sales tax: It's a percentage of the amount you spend. In Ohio Food is not taxable, so buy all the food you want and pay no taxes. In PA clothes are not taxable so buy all the clothes you want and pay no taxes. Live near the Ohio/PA border in WV and you'll really pay no taxes hardly. Low property values in WV, No food tax in Ohio & no clothing tax in PA. You want to quit paying income tax? Move to Florida or NV and get out of State Income tax.
You want to quit paying sales tax, then quit buying taxable goods or buy the cheapest ones you can.
