Less Taxes, More Fun?

“I closed my eyes, shut my nose, and voted Trump”, a good friend told me. To my question of why, he answered “Because of my business”. With this in our minds, let us scan the results of the elections again, and try to understand who voted for Trump and why. There were 131,295,485 votes counted, out of which Hillary Clinton received the majority of votes with 47.71%, Trump came in second with 46.75% and the rest of the candidates trailed way behind. However, Trump ended up receiving more electoral votes, 306, comparing to 232 only for Hillary.
So who voted for Trump? Republicans, naturally, and people who are have more conservative views. A majority of Christians, people who live in the outskirts of large cities and more rural areas and more. The demographic that is most interesting to us is the family income; Trump received a majority (48-50%) of votes among families with an annual income of $50k and over. These are the middle to upper classes, and although they traditionally vote republican, perhaps we have to understand why.
The political right is often unified with more right-wing economic agenda as well, which means less taxes on the rich, big corporations etc. This is why the working class with the lower incomes are “fighting” against the rich, and are pro taxes on them. This is what Hillary and other Democratic nominees have promised them before.
Trump, as a liberal-capitalist individual, as well as a presidential candidate, promised to lower the taxes on the upper class. He himself is an example for it as it has been reported he avoided paying taxes for years. Business owners realise that with Trump as president, their business can flourish and grow, hence they voted for him. So they might not like him a lot, but agree with his financial agenda and voted for him.
Now that the elections are over, Trump already backed down from some of his promises pre-elections. Will he keep his tax cut promises, or will he have a change of heart on this as well?
