There's a way out if you bust your ass and do nothing but obsess about finding something better. Takes a while. Sometimes it takes 18 months just to stumble into an opportunity worth pursuing. Though if you don't put in the effort (and get a bit lucky), nothing changes.
One thing I definitely took away from that article? Holy crap am I frugal. I save a large multiple of #2 for retirement (Solo 401K and IRA maxed every year, with a bit extra on top in a taxable account), and spend about on par with #3. Granted, I've earned what I got so I don't squander it.
As for #4's commute, I've done similarly bad recently, albeit voluntarily. Walk to bus station, take bus one. Transfer to second bus, then walk two-thirds of a mile. About 100 minutes each way, and an average of 3 1/2 hours a day. I could save a wee bit of time with other options (not including car), but at 50-200% increased cost, so I maintained the frugal option even if it cost me another 30-40 minutes a day. Though it does mean that you tend to wake up at 5:45AM to make breakfast and then get to a client for 9AM, to then get home by around 7PM and hopefully have eaten and finished any chores by 8PM. You are beat. It's not easy to then put in extra effort to get other things -- like looking for a better opportunity -- done.
