These are not the same. One is outlawed, the other is not. The words "or other tax" directly relate to paying a tax for voting. It isn't the same at all. To think "or any other tax" is separated out form the phrases that come before it is wrong and an unsupported interpretation of the Amendment.
And what exactly is the connection between the income tax and voting in this proposal? It is clear and unmistakable and beyond dispute: if you do not pay enough income tax then you lose the right to vote. That is 100% prohibited by the 24th Amendment since it not only mentions a poll tax but then goes one step farther and speficially uses the phrase "OTHER TAX".
You are stripping someone of the vote and barring them from voting because of the tax issue and the non payment of it. There is absolutely no difference in any way between a traditional poll tax since the end product is 100% identical, the same and reaches the same result.
Of course Hal, you will simply come back and say "no it does not" asking us if we believe our own eyes and what we read in the COnstitution or do we believe your simplistic responses attempting to pass as fact.
But by all means if you believe what you write, go ahead and back something like this and see what would happen.
While you are doing so you can answer the following questions about this scheme
Just what it is the exact definition of a "net taxpayer"?
How is it measured?
When is it measured?
For what period of time are we measuring?
Which taxes are we considering and why?
Which taxes are we not considering and why not?
Are all levels of government considered?
Can you bounce back and forth between classifications of being a "net taxpayer" and not being one?
How often can you bounce back and forth?
Who will make this determination?
Is there an appeals process?
Is it regularly reviewed?
Is it a violation of the equal protections clause of the 14th Amendment?
Is it a violation of the 24th Amendment?
How many people would be stripped of the right to vote at any given time?
Could they still vote in purely local elections?
How would you manage such a system?
Such a system would make a Mandarin bureaucrat proud.
