Abolish all taxes, introduce VAT of about 30% (while giving the poor some refunds), same income for government, no loopholes/bureaucracy/tax attorneys.
This does not make any sense.
In Europe we have VAT. We pay VAt on all consumable goods and services.
But we also have income tax, inheritance tax...
If 30% VAT should replace all that, the rich will quickly get much richer.
Example:
Person A has an income of about $75,000 and spends that whole amount on food, water, gas, electricity, clothes, insurance, car, fuel... He cannot save any money. So his taxation level is 30%.
Person B has an income of $1,000,000. He has the same expenses, but because he is rich he will spend $200,000 for his more luxurious lifestyle. He will pay 30% on $200,000 and the rest of his income is free of any taxation. He has $800,000 that is not taxed at all.
So the poor pay the maximum and the rich pay the minimum. Even these small refunds for the poor will not make a big difference.
A second problem is that in retail, business owners can put the 30% VAT in their pocket ( as pure profit) on sales that they don't declare. A huge loophole that is difficult to control. Inventories are manipulated to put them in line with the declared sales.
If people would do all their payments with bank cards, it would be easier to control fiscal fraud. A cashless society. The government could control all transactions for each person and see whether the declared income covers all expenses.
One of the ways to escape is using crypto's instead of your bank account. That's why governments will sooner or later intervene in the crypto markets. Tax evasion is, after criminality, the most important reason for the existence of crypto's. Creation of a financial circuit beyond control of governments.
