Why do wind-pollinated plants produce much more pollen than insect-pollinated plants?

The wind does not deliver pollen directly to any particular plant. Polinating insects are encouraged to visit the next flower. The wind deposits pollen everywhere at once. Wind polinated plants therefore have a much greater area to cover, and produce more pollen.

That's an interesting question. If I had to guess I'd say that the wind is more reliable as it is around for longer periods of time. Not only that but it also would carry pollen farther due to a constant force where as insects are slow stop and start implements for pollen transfer.
Reply:Think about it. Insects seek out things, the wind doesn't. So, how do you increase the odds of pollinating other flowers if you don't have anything guiding you there automatically?
