And there's more to governing than boosting the economy. Nor is it even firmly established that Trump's reign will boost the economy. Cutting taxes can boost the economy but not if it leads to massive cuts to spending. Government spending also contributes to growth: the United States' post-war economic boom was supported to a great extent by government spending on infrastructure, for instance.

Then there's the sheer volatility of Trump. As a businessman he showed he could be mercurial to say the least. And he's definitely dictatorial in his management style. Not clear that is going to translate well to democratic government. He may not be able to get anything done.

Then there's all the belligerent rhetoric on international affairs and immigration. He's a bull in  china shop. Chaos as a governing principle is not a productive way to conduct international affairs.

But sure, IF the US economy does well, we MAY enjoy the benefits. Of course, he may also go to trade war with us too.
