Yes, I believe the money grab will get worse. But, with all the legal games they play, they are not in financial danger. They have unpaid slave lawyers working for them. The amounts they are paying with legal expenses to the courts is far less than what they are making in donations.
What is the issue is damnation of the flock. They know that, if someone has money, they can use it for fun. Get a better car--maybe with a couple of features that make driving a bit more fun. Get a better appliance that is going to make work a trifle easier. Say, spending more on an iron that can cut the work time down as much as 30%, or a griddle that makes pancakes or waffles easier to make. Instead, the washtowel insists that such money be donated--so everything will be a drudgery. And that assists them in damnation of souls. The more drab one's existence is, the more a soul can be weakened. This is one major reason they want everything to be so uniform--white dress shirts, a particular style and color of field circus bags, no one standing out among the crowd.
And yes, I believe enforcement is going to increase, stepwise. Congregations that fall short on their pledges or that stint on pledge amounts are subject to audits, as are those who keep funds on reserves above and beyond the tiny amounts allowed. Failing audits, congregations get hounded and the hounders are subject to action. From there, individuals are required to pledge, and if they stint or fall short, they too can be judged. Tracking methods can be imposed to make sure each is donating what they are supposed to, and audits can be imposed so no one has adequate funds to afford a decent lifestyle. Sanctions can be imposed, ranging from hounding to counsel, to disfellowshipping (perhaps on the "brazen conduct" grounds if the initial hounding session does not work), to even having the one judge upholding baptism as a legally binding contract and extorting that they are legally required to pay on the grounds of living up to the dedication contract.
Again, it matters not whether it is financially cost effective. It is cost effective in that they are after souls, not money. It matters not how much they must spend to damn the souls. Most will yield to simple hounding and guilt trips, so they are not going out of business. They spend more on those who refuse, threatening with judicial action--that will work on most. For the few that even that doesn't work, they resort to suing (remembering that baptism is a signature to a contract of dedication to joke-hova, and it only takes one bad judge to uphold it). Even if they spend 100 times more than they receive on those individuals (not financially sensible), they still damn the soul--and that is what they are really after.
