It actually doesn't hurt the poor, it hurts the middle class. Highly wealthy individuals make most of their money through capital gains and selling property. They tend to have a fairly low income relative to their actual wealth. 

The the poor have such a low income that when accounting for tax credits, they end up paying 0 in taxes. If you consider the benefit of public goods they get, they're getting a net gain in taxes. 

The middle class foots the income tax bill as you have enough to actually get taxed but not enough wealth to dodge income tax through assets.

In a way hurting the middle class ends up hurting the poor as well. Middle class individuals with more money usually leads to more small businesses which translates to more competition for workers. Less variety in employment leads to either working at Walmart or Amazon who can now pay their employees less. 

I like a property tax on stocks to stop the non stop investment that happens into big corporations.
