There are 24 hours in a day, and 8 should be spent sleeping.
That leaves 16 hours a day to be awake. In 7 days, that's 112 hours a week to use wisely.
This Watchtower graph is split into 6 equal parts. 112 hours divided by 6 activity groupings is 18.5 hours. This is 18.5 hours a week to devote to each subject area.
A job on 18.5 hours a week? Remember, most Jehovah's Witnesses do not have a college degree and can not be high paid consultants. If fortunate, say they earn $15 an hour. At 18.5 hours a week, that's a meager $270 a week, or $1,080 a month! That, will surely feed and house a nice family? LOL.
What's puzzling is the block for meetings. Meeting time has been reduced, and is now about 4 hours a week. So, what is the Witness going to do with the extra time? It doesn't take 14.5 hours to study for or commute to meetings. And, field ministry and personal study have their own time blocks. So, is the Watchtower about to propose a change in the individual Witness lifestyle? Are longer meetings in the future?
At 18.5 hours a week for ministry, that puts everyone as Pioneers! Weren't the required hours just reduced?
Does the Watchtower really want to devote 18.5 hours a week to personal study? Could leave to the followers finding more fallacies.
Obviously, with the exception of Bethelites, very few Witnesses are spending 55.5 hours a week (that's 18.5 * 3) in meetings, ministry, and personal study.
The purpose of this Watchtower appears to be to place a further 'guilt' trip on those who are struggling to make ends meet and be good "Christians." The Watchtower is always raising the bar, and this is an attempt to make those with full time jobs "feel bad" about their choice to feed and clothe their family. Obviously, these working stiffs are depressed because they are taking time away from personal study, ministry, and meeting attendance to have a job.
How does this pan out for school children and teenagers. Try going to school for only 18.5 hours a week. Even if you are "home schooled", this is likely not going to meet education mandates.
