I agree with your first sentence, but a sales tax is not regressive. Rich people spend more than poor people... much more, usually. This is especially true since food and rent are generally exempt from sales tax. Many states also have exemptions for clothing or clothing up to a certain price.
The sales tax is a very progressive tax.
I don't think so. Progressive means higher percentage, not the same percentage.
The sales tax is not progressive in structure in the sense that it is the same percent for poor and rich, in contrast to a progressive structure with income tax, for example, where higher incomes are taxed at a greater percentage.
Further, the sales tax is actually regressive. Indeed, the poor generally pay a greater percentage of their income in sales tax than do the rich. In other words, the more rich one is, the more likely they save (not spend) a portion of their income, whereas the poor generally spend all of their income. Thus, as a percent of income, the poor pay a greater percent of their income on sales tax. For example, for a 6% sales tax, if a rich person spends only half of their income, then 3% of their income is being collected as sales tax. In contrast, for a poor person spending all of their income which is usually the case, then 6% of their income is being collected as sales tax. A regressive tax.
Moreover, the rich and poor both get the same exemptions on food, clothing, prescriptions, other items, rent, etc., if such exemptions exist.
The poor do generally rent more than the rich, which a rent exemption could offset the regressive nature of a sale tax somewhat. With that said, most states collect sales tax on rental personal property, and even some states such as Arizona collect sales tax on rent for apt/homes.
It is open to debate, as indicated in a comment in wikipedia:
"Some people consider sales taxes to be regressive; that is, they believe that the tax imposes a greater burden on low-income families than wealthy families. However, it has been suggested that any regressive effect of a sales tax could be prevented, e.g., by excluding rent, or by exempting "necessary" items, such as food, clothing and medicines."
