There are several modes of transportation that a given individual can utilize on any given day such as an automobile, bus, train, subway, or airplane; but it is only those that travel via airplanes that have to suffer through endless bureaucratic security lines that often seem disorganized, inconsiderate, and completely pointless. The reason for being for these security lines is in theory to help keep us safe, but it seems simply to serve no other purpose than to waste countless hours of time from everyday citizen's lives without any real effectiveness.
Not too surprisingly, just like about everything else that happens in America, security lines, and how you have to deal with them, depends a lot of whom you are. That is to say, if you work for the government, the military, an important corporation, have money to spend on privileged treatment, or a person with real connections, and so forth, you aren't going to be treated like a "commoner" when arriving at the airport, instead, you will be permitted to walk though expedited lines, because you are special, or have paid extra money, or gone through some sort of vetting process, which allows you to circumvent the airport security lines set aside specifically for the rest of us.
This means, in effect, that there are two basic classes of people at the airport, those that are treated differently as special and privileged people, whether through connections or a monetary payment, and those that have to suffer through circuitous lines, harassment, body scans, pat downs, and the general annoyance of being treated as "presumed guilty" when going through security. Because of the fact that people are treated differently depending upon their security classification or status, the situation for most of the citizens of the United States at airports, is rather intolerable, while for those that don't have to go through the time wasting and indignity of being treated like sheep, are blithely unconcerned, and feel that this sort of special tribute given to them, is the least that their country should do for them.
In theory, this is supposed to be a country that treats all of its citizens equally, with laws equally applied, but airports are a prime example of how this is completely untrue. While the government can give or site all sorts of reasons for allowing TSA Precheck, and other assorted programs, that allow certain people to have privileges, and thereby are given a green light of "presumed innocence" while all others, by virtue of the fact that they are none of these things, are all grouped as "suspects", that sure doesn't seem right.
When laws are unequally applied and those that write those very laws and their most important constituents to them are the primary beneficiaries of such laws, than those laws will not be changed, because the power brokers of America are unaffected by them; whereas, if it was the other way around, that the elites of this country in order to fly commercially, had now to be subjected to immeasurable lines, basic disrespect by security personnel that their taxes pay for, as well as groping and strip searches by these very same poorly trained and weakly reasoning personnel, then it all would change the very next day.
