It appears relatively easy to get a majority to vote against their best interest. Case in point: Trump getting elected. If all that's needed to win a vote is populism and ad money, then you can be damn sure that people will vote not just against unalienable rights of minorities but will also against sell out their best long-term interests to short-term ones or to "principles" that sound good because they've been constantly repeated on Fox News or CNN.

Even without demographics taken into account, a country that's not accountable to a base set of unchangeable rules is a scary thing.

I honestly don't really think you've thought this out.

You might want to understand the existing structure of government before you propose replacing it on a whim.

Here are some questions to get you started:

* Why is there a Constitution?

* Why are there 3 co-equal branches of government? What are they all there for?

* Why is there an electoral college?

* Why are Senators allocated by state while House members are allocated by population?

* Why do House members have 2 year terms and Senators have 6 year terms?

* Why do the courts exist?

* Why does the executive branch exist?
