Ahem. The logic behind these state/federal subsidies is that the govts avoid the environmental/legal/infrastructure costs of building more utility plants. Seems cheaper to just let a few foresighted individuals keep their money instead of raising everyone's taxes (or electric bills) to pay for more problem-creating industry.Or tens of thousands to install solar panels.
Judging from your loophole-detection and -exploitation prowess, I'm pretty sure that the govt has reaped more of the taxable benefits of your knowledge & critical-thinking skills than they ever loaned you to acquire that education (plus whatever the school tried to teach you). Or at least they've given you all that money now in hopes of not having to pay you unemployment/welfare later. I can support that.
It's rare that the common taxpayer gets a chance to do to the taxing authorities what they regularly do to the taxpayers without a second's hesitation. This is the byproduct of misaligned incentives...
