Seeing that Trump has became the first president to be impeached two times, how do you feel about a president getting impeached after he has left office? 

Tough question to answer.

Explanation:

This is a tough question to answer. Although it is in the Senate's constitutional right to conduct an impeachment trial, the Constitution states an an impeachment is only for a sitting US president and does not have much guidance for a non-sitting US president. As of now, Donald Trump is a private citizen and therefore the impeachment may not directly effect him in the same way as a sitting US president. However, an impeachment where he is found guilty will disallow him from running for office again in the future.

Although there are many arguments and opinions to this particular subject, the current impeachment seems to be more politically motivated than actually needed.

It seems that you have missed the necessary options for us to answer this question, and i cannot find it too. anyway,  the new industrial state   is a 1967  book   by john kenneth galbraith. this book relates about the economics of production and its effects. hope this answers your question.
