This statement can be considered incorrect because the person is not taking into account what the actual effect of the sales tax and the excise tax is on consumers. The excise tax is a tax applied at the moment of manufacture, not at the moment of sale. On the other hand, a sales tax is applied to a product at the moment of sale. However, if companies have to pay an excise tax, they are likely to raise the prices of their products, which could end up having the same effect on consumers as the sale tax. The person has most likely overstated the effect of the sales tax, while understated the effect of the excise tax.
