Because people lose money when they serve on a jury, the jury is usually composed of those who have nothing to lose such as those who have no jobs or are retired or otherwise able to take the time. Also many will do anything to get out of serving. Things need to be revamped so a jury is representative.
It is possible for the United States Justice System to improve jury duty if they just tried. They don't even try or care to improve it but they could. They could pay people more for being a juror because it is not easy and most people suffer a hardship when being a juror.
I believe it is not only possible, but necessary for the United States to make improvements to jury duty. One of the most difficult things seems to be finding an impartial jury. In today's world it is impossible to find people who are not already aware of the facts in any given court proceeding. Perhaps it we should completely rethink the way we sit a jury. Perhaps we should sequester the jury and provide them with computerized text of the trial and ask that they make their decisions based on that instead of spending their time in the courtroom.
If the United States Justice System wants to improve jury duty, all they have to do is have a more strict picking system, and only choose citizens who are highly educated, and are not racist. As it is now, almost any citizen can be picked for jury duty, even the uneducated.
Yes, it is possible for the United States Justice System to improve jury duty, because there are ways they could adjust jury duty to be more efficient. Especially in the federal system, there are people who have to drive hours to get to their federal court when they are called for jury duty. The drive is very unfair.
