So basically businesses would charge a sales tax (3%) increasing prices for the consumer.
Then the consumer would also pay 3% income tax. The consumers would pay 4% wealth tax. The business pays 3% revenue tax, taken from the consumer. The business wouldn't pay 4% wealth tax. Essentially the business would pay 0% tax, and the consumer would be on the hook for it all.
So a person who earns $50,000 and saves $20,000 per year would pay the following: Year 1, $1,500 on $50,000 Year 2, $1,500 on $50,000 $20,000 from previous year saved - 4% tax $800 a year $2,400 in total taxes. Year 3, $1500 on $50,000 4% on $40,000 = $1,600 $3,100 total tax
By year 20, the consumer who would have accumulated $400,000 would end up paying a total of 170k in taxes on savings, resulting in almost a 42% tax rate on their wealth.
