Your social studies teacher misinformed you by telling you Congress had the power of the purse. Congress can refuse to appropriate money but the President can can prevent Congress from appropriating any money as we have just seen in the shutdown.
congress can over ride the presidents veto, which is the last hand that can be played.
Trump will go nowhere with his 'manufactured' National emergency powers because there IS NO EMERGENCY.... and will be stopped by the courts via a 'stay' until it works its way through the courts.

noun: emergency; plural noun: emergencies
a serious, unexpected, and often dangerous situation requiring immediate action.
The President's power to declare a national emergency is defined by a group of laws passed by Congress in saner times, and under these laws an emergency is anything the President declares to be an emergency as long as he follows certain procedures such as advising Congress of what he is doing and why he is doing it.
okee dokee.... come back and say you 'own me, and I'm your *****' if it is not stopped by the courts... but my bet, is it will be, immediately ''stayed'.
What do you imagine would be overturned by the courts?
I'm not certain... maybe it could come as a suit from land owners? but a veto proof congress could stop it... the House is a given, and the Senate is a possibility.... many republican senators do not want the president to declare such as a national emergency because they believe it is an abuse of power and opens the door for future presidents to claim global warming is a 'National Emergency' and similar things they disagree with....
You talk as if this is an unusual thing. National states of emergency have been declared over 500 times since the beginning of the republic and 58 times since the current legislation was passed in 1979. 31 of these states of emergency are still in effect.
"Congress has delegated at least 136 distinct statutory emergency powers to the President upon the declaration of an emergency, with only 13 of these requiring a declaration from Congress.

Emergency presidential powers are dramatic, and have ranged from suspending all laws regulating chemical and biological weapons, including the ban on human testing (
50 U.S.C. § 1515, 1969); to suspending any
Clean Air Act implementation plan or excess emissions penalty upon petition of a state governor (
42 U.S.C. (f) § 7410 (f) 1977); to authorizing and constructing military construction projects (
10 U.S.C. (a) § 2808 (a), 1982) using any existing defense
appropriations for such military constructions ($10.4 billion in FY2018
[16]); to drafting any retired Coast Guard officers (
14 U.S.C. § 331, 1963) or enlisted members (
14 U.S.C. § 359, 1949) into active duty."

You may not be aware of how common declarations of national emergencies are, but members of Congress are, or should be, so it is nonsense to talk about Trump's state of emergency setting a precedent. As for trying to rescind the laws giving the President the power to declare a state of emergency, it is doubtful the Democrats could scramble two thirds of the House to back that effort and certainly they couldn't find the votes in the Senate.
