I'd say "Consumption tax is equal for everyone."Perhaps change number four to ... choosing a less expensive product.

1: Consumption tax is equal FOR everyone.[to = wrong preposition; tax equal "for who" not "to who".]2: Regardless of our age, gender or status, people pay the same amount of consumption tax when buying a product.[ or = conjunction; saying just people is enough as people already is plural; we still pay the same tax, it hasn't changed. So, it should be pay instead of "have paid"; "when they buy a same product" was not worded well.]3: Rich people who can afford luxuries like jewelries, top brand articles and imported cars should pay a lot of consumption tax because ---- [ it has a same rate on every product. ] ?? - your idea or what you are trying to say is unclear after because. Do correct it.4: Struggling families can cut down expenses by choosing the inexpensive products.5: Other taxes - such as: corporation tax and income tax - are unequal because they categorize people into different groups, whereas, consumption tax is flat enabling it to be raised evenly among citizens. Hope it helps.
