Opponents of a proposed tax claim it could lead to new taxes on many people. They argue that lawmakers might expand the tax to apply to individuals with less wealth. A key point of contention is language that allows the legislature to amend the tax with a two-thirds vote.

This amendment could potentially change the tax's scope. The concern is that it might no longer only apply to a specific group of wealthy individuals.
