The Enumerated Powers give Congress a lot of power. Article 1, Section 8 lists powers specifically left to Congress. This includes the power to declare war, raise and support armies, and lay and collect taxes. It also includes the Elastic Clause, which allows Congress to pass laws deemed "Necessary and Proper."
Those "stupid" subpoenas are very powerful actually. If the President denies the subpoenas, it goes to the judicial branch. You aren't answering to your own branch; you're answering to the legislative, and when the president tries to avoid that, you answer to the judicial branch.
Nixon was scared enough to resign before they could remove him. Also, the troops can only be there for so long before CONGRESS has to decide whether or not to declare war. That "power" only lasts for 90 days; then, it's up to Congress.
Congress is more powerful because of Power of the Purse. “All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with amendments as on other Bills.”— U.S. Constitution, Article I, section 7, clause 1. The president can't even create a bill.
Since Congress has the power of impeachment, it is more powerful than the president. If the president does anything remotely suspicious, Congress can look into impeachment. Even if the impeachment does not go through, it creates bad publicity. For example, the word impeachment associated with our current president, Donald Trump, could have a major impact on the outcome of the 2020 election.
What exactly will "limit" said jurisdiction? The government itself. The government could EASILY use that to its advantage. The central government keeping itself in check? That sounds like letting a five year old be home alone all day with no babysitter and expecting them to get onto themselves when they do something wrong.
It is not necessarily wrong to fight for what's best for themselves, nor is it selfish. If each state focuses on their individual needs, the country as a whole would be thriving.
If we centralize the government, it will not be as functional. It is better for the states to have more power because they have the people and the individual state’s interests in mind. With a smaller group of people to focus on, the state governments would be better fit to suffice the needs of their own people, whereas the government as a whole focuses on the population as a whole. This prevents problems in specific places from being brought to light.
Essentially, the Necessary and Proper Clause is too broad; it gives the federalists the ability to create just about any law at any time they see fit. This can easily create a corrupt government. If the government has all of the power, any law is fair game, which can become dangerous fast.
Our problem is not with one branch being too powerful, it is with the government as a whole becoming too powerful. What keeps the government as a whole in check? We elect people. However, our power ends there. We get no say in what actually happens, just who decides. Your last sentence is our problem with "your" government. Ours is not weak. Ours deals with problems specific to our region. Like you said, your new government is pretty powerful. We just hope it doesn't get too powerful.
