“All income earned in the lower bracket is taxed at the same rate...All income earned in the second bracket is taxed at the same rate...All income earned in the third bracket is taxed at the same rate”
Why are you only comparing people within the same bracket? Quote me ever saying they’re not taxed equally. Try comparing an individual from bracket two to an individual in bracket three. See what I’m getting at. They have different rates, which means different rules apply to them.
“The fact that you may not earn enough to get into the second bracket or the third bracket doesn’t matter”
Yes it does. For it means you are taxed at a different rate or maybe not at all.
