It's a cash-flow thing.
They have hundreds of millions, tied up in long-term investments (imo based on some of the areas where they have to report financials). When I say long-term investments, I mean 10 or more years till payoff. Things like annuities and such.
They scream poverty, but they will never reveal how much they have tucked away. I guarantee you they didn't put their annuities and such up as collateral for the construction loans. Those loans are based on a certain cash-flow picture they promised to the banks.
Jehovah didn't bless them as expected :) They refuse to collateralize their investments. So they have to deal with the banks shutting down a large portion of their projects.
The WT complaining about money is like a rich person saying "I can't afford it". When a poor person says that, it means the poor person couldn't buy it if they wanted to. When a rich person says it, it just means they haven't budgeted for it or simply don't want it.
