The time and money you spend on entertainment is an expense, not an investment. Linden Lab is not a bank. You don't earn dividends or interest on the money you pay them for their services.
No, I do not earn dividends but what I do earn is a very substantial living out of SL. I just filed my taxes and I made a mere 2000 USD less in SL than I did at my full time real world job as a veterinary technician. So yes, I take extreme issue with LL messing with my ability to make the living I do. This is not entertainment to me, it's how I eat and pay my mortgage every month.
