I think that the problem is that we are looking at long term and you are looking short term. Yes, until the difficulty increase the time to find a block would decrease. And you would continue to find them at a constant rate. But, when he difficulty does go up, it will more than compensate for the previous "gift". At least i think it will. there are those that speculate that the date the last Bitcoin is mined is slowly moving closer.
I completely agree - but thats exactly what i said before. If someone else adds hashrate, my reward stays the same _until difficulty adjusts_.

Okay, we are getting near.
Lets say we have two pools, each with half the hasrate (say, 10 GH/s each).
Both find a block every 20 minutes, totalling for one block every 10 minutes.
Now one pool adds 20 GH/s. Network hashrate is doubled, blocks are found every 5 minutes.
One pool has 30 GH/s, tripled hashrate, finds 3 blocks in 20 minutes.
The other pool stays at 10 GH/s, finds one block every 20 minutes.
In total, 4 blocks in 20 minutes -> one block in 5.
One pool gets same number of blocks with same hasrate, so same income as before for all its miners.
The other pool gets three times the blocks, but every miner in it now has only one third of the relative hashing power, so he gets one third of his usual rewar per block -> same income as before.
I agree with you, only "in the meantime, your reward will have dropped" i cant see.
