Do you do like 5 faucets and quit? You should easily be able to make over 1 dollar an hour using faucets. If you can't you are doing something wrong. I just spent about 5 minutes the other day and was easily able to make 30 cents.
You should be darn close, if you aren't you are doing something wrong. You roughly get anywhere between 1000 satoshi and 2000 satoshi on most faucets. Each faucet roughly takes 10-15 seconds to do. Say you can do 4 faucets per minute for a rough average of 1500 satoshi per faucet. So you should do 4*1200 per minute, roughly at 6000 faucet per minute. 6000 * 15 = 90,000 satoshi per 15 minutes. For the record I also didn't say you could earn a dollar per 15 minutes, I said per hour.
