No one going into government who plans to cooperate with that government will change the government. They will be changed by the government. Only a person who is deeply principled and unwilling to compromise on their principles can save themselves from the government. Such a person will be an inspiration to the people but they will accomplish nothing until there is a majority of such people in government.
At this point in time, no one who is right for the job would want the job. They would simply be responding to the compulsion to try to save others. They would be sacrificing themselves.
For evidence of this reality we only need to look at:
→ President Trump`s treatment by government
→ the inability of weak Republicans in the House to affect government.
