The anti Imperialism league took a dim view of imperialism which meant they opposed the expansion b/c they believed imperialism violated the credo of Republicanism,especially the need for " consent of the governed."
There wasn't enough money in circulation to support a healthy economy.<span> And was a result of the bank failures that followed the stock market crash in 1929</span>
The separation of powers was the first step to limiting power for one branch. The US built up their government based on the British, in which they had their version of Parliament, called Congress, the Federal Judge, or supreme court judge (as well as others, but we are focusing on the supreme court), as well as the executive branch, which is the President.
The next step was "checks and balances", which ensured that no one branch can be too powerful. The US president can veto Congress's legislation, Congress can override the veto, they can also impeach the president. The Supreme Court can rule laws unconstitutional, and change the laws based on what they think is constitutional.
hope this helps
