First, trading options is a viable form of serious income. Yes, you can trade options but you need to be careful what you trade. If you want to, trade the overall market options (QQQQ, SPY). These are as liquid as options get and provide reasonable spreads.
Second, the spreads are huge because the risk for the market maker is huge. Consider HWAY the other day, $35 Puts went up over 2000% and somebody had to foot that bill. The spreads are necessary so the MM doesn't get blown out of the market when one stock moves against him.
