Donald Trump came out of nowhere because he saw the USA as being like an insurance project: a property occupied by those who are not making the most of it, it could with a little improvement become much more valuable, which would in turn help him and everyone he knew.
This caused great panic in the Establishment, because all of them benefited a great deal from the cozy relationship where Democrats produce vast bloated programs, Republicans pretend to fight them, and then everyone agrees on how things will be and then goes off to the bar to celebrate.
Politicians can do this because the law is cumulative. Once you pass enough Leftist laws, like the Fourteenth Amendment, Hart-Celler Act, and Civil Rights Act of 1957, you are locked in to passing more Leftist laws because your social movement that approves of these laws has increasing momentum.
In addition, you must consider procedure, especially that outside of written law. In America, that means finding enough donors to sponsor your campaign, and then enough allies to get things done, so that you can do what every careerist does: make a name for yourself by passing more laws, however useless.
This means that Washington moves according to rhythms. Where you are in the election cycle determines everything; the quality of your bills determines nothing; the celebrity value of the topics on which you are legislating determines how famous you get and through that, how long you stay in power.
If you do not get a strong brand and acquire the right donors, you are toast. They call the recognition of that “professionalism,” but really it means working the job instead of having the job work you. Figure out what is required, and check off that list, and you succeed.
This requires not caring about the consequences of your actions. Does the bill work? Who cares, it is popular. Anyone who does not accept the status quo — market socialism, world police, diversity, equality — as good gets filtered out long before they have a chance at any higher positions.
Denialists see this as a feature, not a bug, of democracy. In theory, the politicians are accountable to the people, so the politicians do what is popular. In reality, politicians realize that the voters are nitwits who like being lied to, and become very cynical and manipulative people.
To these careerists, their relationship with their coworkers is more important than any ideals they may have. This is a job, not a calling. They do it for the power, because with that they can get money or anything else they want very easily.
In addition, they use different vocabularies. Leftists are at home in egalitarian systems, and democracy is one, because to them, the popularity of an idea is all that matters. They want the power of having a mob of people behind them, as opposed to facing a revolution head-on.
Conservatives tend to view government as a business, which it is. To them, the point is to keep the business from running into full dysfunction or bankruptcy. They are not bothered however by a certain amount of debt, bloat, and incompetence, because this is the nature of government.
The only good leaders we have are dabblers in politics. They are not as slick as the true professionals like Bill Clinton, mainly because they are not criminal. To them, politics is a means of achieving certain ends that will benefit the nation, because this the path to glory.
