They are already demanding pledges toward special projects. Back in 1996, I was handed a pledge form for a Kingdumb Hell project that I did not want to donate towards (let alone commit to a monthly donation). I "forgot" it at home the day I was supposed to turn it in, and they shoved another one in my face and demanded that I fill it in on the spot (with the hounders watching). I told them that, either I would take it home, or I would put "zero" on the amount and hand that in. I took it home--this time, not only I left the pledge form home but I stayed home with it.
At some time in the foreseeable future, I can see them expecting pledge donations all the time. The hounders will decide how much they expect you to donate on a monthly basis (and they have no room for error). If circumstances improve, they up the amount. If circumstances get worse, you still have to "trust in Jehovah" and continue donating the original amount. Anyone falling behind in their donations will be subject to a call from Brother Hounder about "stealing from Jehovah". I expect this sxxx at a$$emblies, so they can maximize the donation to the Worldwide Pedophile Defense Fund and then require them to use credit cards to pay the bills at the last minute.
Pio-sneers are already forced to pledge a certain number of hours of field circus a month. If they do not make their time, they are in for a call from Brother Hounder about it. They promised to do 50 hours a month (or 70, as the case may be), and if they do not fulfill it, they are treated as if they welshed on purpose. Never mind that they spent three weeks in bed with the Spanish flu. Never mind their house had a fire and they had to rebuild. Never mind they had to hunt for a job, or they just got a job unexpectedly (cutting short their unemployment, but also cutting short their month of getting 50 hours).
I am led to believe that anything is possible in the future. They could start treating baptism as a legally binding contract, enabling them to go after (and sue) anyone that later fails to put in field circus during a month or that breaks one of the rules. They could start going after and dragging back people that have lapsed, even if they are doing apostasy. What they do at that point is up to them--sue, disfellowship, host and drag in field circus, whatever they see fit.
Already, there are rules against everything fun. The Filthful and Disgraceful Slavebugger has articles against worldly dress, spending time alone with a member of the opposite sex, masturbating, listening to "bad" songs, watching R movies, going to college, buying a 2-door car or decent material things, and hanging out with worldly people. Some congregations, and different hounders within each congregation, have different additional rules. Some have little or no tolerance for transgressions on these "conscience matters", while others will let it slide. Some have zero tolerance for transgressions by certain people (like those they are trying to get into the Value Destroyer Training School) while others will get away with it.
