Why is a retail sales tax of 4% not proportional but regressive?

category

economics

options

  1. The 4% retail sales tax decreases in percentage as the amount spent on consumption increases.
  2. The 4% retail sales tax is regressive because it applies only to luxury goods, which lower income groups do not purchase.
  3. The 4% retail sales tax is a flat tax, so it affects all income groups equally.
  4. Lower income groups receive a subsidy that offsets the 4% retail sales tax.
  5. Higher income groups pay more retail sales tax because they have more income.
  6. Higher income groups are taxed at a higher rate with the 4% retail sales tax.
  7. Lower income groups are exempt from the 4% retail sales tax.
  8. The 4% retail sales tax is proportional because everyone pays the same rate.
  9. The 4% retail sales tax is adjusted based on the buyer's income level, with higher incomes paying a lower percentage.
  10. A 4% retail sales tax is regressive because lower income groups spend a greater proportion of their income on consumption, resulting in a higher effective rate of taxation for them compared to higher income groups.
