T, you're correct on both counts. Speculation is already under way regarding which of Obama's executive orders will be immediately rescinded by Trump. But an executive order issued early in Trump's administration will be in place for most of 4 years and could do a lot of damage. For example, a lot of children in our area receive meals at school and for some of them, that may be the only time they eat. It would be well within the president's authority to issue an order abolishing the school lunch program. Does that sound like something that might impact our daily lives?
Of course, Congress could pass a law re-establishing the school lunch program but we have a Republican Congress and even if they did pass such a law, the president can veto it.
Another example of how the president can directly affect our lives. The president has the right to appoint a new chair and co-chair for the Federal Reserve Board and will also be appointing several FRB members. He could choose to sway monetary policy, which is currently set by the FRB, by appointing people who are in favor of a tight money policy. The FRB could then raise interest rates, slowing the economy and causing large numbers of people to be laid off. Or he could do the opposite, appoint members who are in favor of opening up the floodgates, boosting the economy to the point where rampant inflation occurs, the price of everything goes up, and your dollar becomes worth less and less. Far-fetched? Maybe, but Trump has been openly critical of the FRB.
What else could happen by executive order? Perhaps an order mandating that Muslims be required to display a crescent somewhere on their clothing for national security reasons. Or maybe just create camps and send them all to live in those camps. While we're at it, he could order that the LGBTQ community be required to wear rainbow colored necklaces to protect our children from their influence. Of course, these things would create controversy but controversy doesn't seem to influence Trump.
It's true the president can't declare war. Only the Congress has that right. But he can send our troops off to fight for up to 60 days without Congressional approval. With the weapon systems we now have can you imagine how much damage could be done in 60 days?
The president can also influence foreign trade and Trump has advocated tariffs on foreign goods. Do you suppose it would affect people's daily lives if everything that we import from other countries suddenly experienced huge price increases? What do you think that would do to the world economy?
I know these are worst-case scenarios, but we now have a President-elect who follows his own path and has shown a low tolerance for people or ideas he doesn't approve of.
