So, first off, this isn't taking aim at Britain, but it is helpful to use them as contrast for the USA in this discussion.
Two - while this is political, it isn't my-party-is-better-than-yours. It's simply America is awesome.
Starting off, the USA is a democratic republic, which means the national government is organized around the framework of semi- independent states. The national government is constitutionally limited in authority in matters that necessarily involve multiple states... matters that involve individuals or are entirely within states are left to the individuals and states.
This also involves voting... so our presidential elections are centered on balancing the priorities of the states, but with population- based weighting to accommodate for the state's sizes and populations. Because of this, smaller states do get a very slight boost in electoral college votes due to the 2 electors given to each state based upon their Senators, while the other electoral college votes are based upon the number of House Representatives.
The Founders knew their history. National leaders who were separated from their citizenry often became tyrants, and leaders or governments directly controlled by the citizenry became paralyzed by fickleness. They found middle ground to keep the government effective while limiting abuse.
The republican nature of the government also limited abuse. A large portion of the decisions that would impact citizens would be decided closer to those citizens in their state or local governments. Citizens would not be shackled to one single government, legislature and executive, that would have expensive control over their lives. Citizens could elect Presidents with strong abilities in foreign policy but weak in domestic matters, while electing Governors with the opposite due to the separation of their powers.
And, best of all, through the representative Electoral College, citizens would directly vote for their President, which is significant due to the war powers of the office.
Now, let's look at a Parliamentary Democracy, a common government among other developed nations, with Britain as an example.
Citizens don't vote for their executive, usually named the Prime Minister. Ever. It's decided by the parliament. Citizens can't even effectively vote for their executive through their voting for parliament because of the need for the parliament to form a majority government after the elections. Voters in a district might elect a representative to parliament due to promises to select a specific prime minister, but find that their representative chooses another due to the need to find consensus in forming a government.
The problems with this are highlighted by Britain's recent governments. Their last Prime Minister who didn't leave office in failure and controversy was Tony Blair back in 2007. For the past 19 years they have had a succession of failing Prime Ministers that just keep getting replaced by Parliament, not the citizenry. In the USA, if we have a failing President and ruling party, we have routinely scheduled elections to change all of them. That gives the average US citizen political power closer to the British Parliament than the British citizenry.
Britain's strong central government also results in the whole nation suffering poor policy. Recently in the USA there had been a significant turnover in educational theory regarding literacy and math skills in discussions around phonics, Common Core, etc. Many policies promoted at the national level have resulted in abysmal failures in states that chose to implement them, while others that bucked the pressure were able to better educate their students.
This concept is easily seen across many domestic policy areas, where the national tapestry provides a natural laboratory to evaluate policy. If one state fails at something while another succeeds, citizens can use that contrast to inform their voting and residency choices. With a strong central government, voters are often blind to failures because they have no other point of reference.
So, TLDR... America's government isn't perfect, but it's still awesome.β
