Wind can be profitable. In fact, a local town just built a brand new GE windmill. I've read through the documentation on it, and interestingly enough just like a small business venture it's expected to earn no profit for around the first 10 years. After that however, it is expected to turn a profit. On top of that, "ideal" conditions is probably a wider range than you give the technology credit for. Modern wind mills have gearboxes in them to drive the generators at appropriate speeds so long as the blades are spinning. On top of that, due to wind gradient the winds above treelines and the like are faster overall, so while we may not feel much on the ground there is almost always wind a couple hundred feet up.
That statement makes me think that you don't know that there was almost $200,000,000 in tobacco subsidies given out in 2011. I'm sure we can all agree that there is a vast market for tobacco and tobacco products in the US alone, never mind the rest of the world.
What about the vast amount of subsidies given to the oil industry?

Subsidies are probably just not that easy to define what they do and do not apply to. Industries from all spectrum of profitability benefit (and many abuse) subsidies, and they don't only apply to business which are not profitable or do not have market support.
