Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies. Although it may take a while to get your head around the concept, Matched Betting can make a substantial addition to your monthly income.
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer with a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
Pessimism is coming from the media! Good news is not newsworthy. Some of what you are describing is regional. Do you think things are that good in a city where there are plant closings or an industry with high unemployment?. Not all professions are doing well! I think you are describing successful people rather than the economy. Success generally has very little to do with how everyone is doing. I go to some of those crowded restaurants too. I wonder if the sales are the same or just busy. Everyone could be spending less than before.
