Of course it is. This nation's system has always been one that accommodates the wealthy and leaves the poor people even poorer at the end of the day. Trump is not going to do anything different than the rest of the republicans have done. President Trump equals President more of the same.
Trump thinks in the short term. His campaign proposes plans and produces strategies to improve the likelihood of Trump being president, not for the sake of creating a better America or a better world. Based on what I've read so far, apparently Trump's new plan taxes proportionately. So, if you are wealthy, you will be paying more than your less wealthy neighbor. This makes it difficult to argue that Trump's plan benefits the wealthy.
Trump's tax plan is more of the same old Republic strategy--not because it necessarily benefits the wealthy. Like Republicans before him, to keep his Party's support, Trump cannot cut certain parts of the national budget, like defense. So, he would cut into education or other socially important sectors. He attempts to make up the difference, the social implications, by raising taxes and, thus, endanger the economy. Before winning the nomination, Trump had a different tax plan. In the newer plan, every American would pay more. There are certain benefits, according to his campaign, for the middle class. But economists are saying that this plan will put the country in more debt.
Trade will help the middle class in Trump's plan, even if the tax system doesn't change much for them. His plan is to help bring a great amount of jobs back into the US. Most republicans would never agree to raise taxes much on the wealthy. Unless he wants to alienate all republicans he won't want to tax the wealthy much more.
Trump's newest tax plan offers benefits for the middle class. The tax rate for the middle class would be cut from what it is currently.
He proposes making childcare expenses, which are a large expense for much of the middle class, fully tax deductible. He also has said he would consider a payroll tax holiday to assist the middle class.
