Two Jobs and Retire Early?
70_hours_week wonders: "A Survey of teachers in a Nevada school district indicate that 40% have a second job. Do you have a second job? Assume you are 30 and since you like to save your money you could semi-retire by age 50. Now, what if you could nearly double your salary working a second job and that meant you could semi-retire at age 40. Would you do it?"
Personally, I see the US undergoing some serious inflation over the next 40 years. If I had to work a second job to just barely be able to 'retire' early there's simply too much risk involved to make the potential pay-off worth pursuing. If inflation does take off, savings will be decimated.
If you want to retire early, get into something that pays really really well. Then hedge your risk by moving a chunk of your wealth out of dollar denominated assets. If you're smart enough to be an engineer (or even an IT generalist) then you're smart enough to be a successful stock broker or banker (think leveraged buy outs).
My point is that the risks we all face are great enough that I wouldn't be willing to sell the prime of my life to a second employer unless I was damn sure that my retirement was going to be comfortable and satisfying (Viagra gets expensive over 20-30 years, yo).
As has already been pointed out, many of your assumptions are invalid. You can scale your idea back a little bit and find some more modest success. Typical retirement advice is to set aside 10% of your income throughout your entire career, but anyone with a clue knows that compound interest makes your early savings exponentially more valuable than the savings from the end of your career. If you were willing to bust your hump for 5 years and set aside 5 times as much as you normally would, you might be able to coast through the remainder of your career knowing that your retirement is already handled. It's unorthodox, but it might work. Do your homework.
Now, what if you could nearly double your salary working a second job and that meant you could semi-retire at age 40.
Double your salary? This isn't possible for any sort of professional career that I know of. Most careers that provide any sort of decent income take more than 40 hours a week.
The only "get another job, double your income" kind of positions I can think of would be menial jobs. If you're making $6/hour putting in 20-30 hours/week at Burger King then yeah, I'm sure you could do another 20-30 hours a week at another burger joint. But that's not the kind of money you can retire on. I mean, you can barely live on that.
The teacher in the article isn't retiring early either, by the sound of it. And she's sure not doubling her money. Sounds like she's supplementing her teaching income by working other jobs just to make ends meet and provide for her kid.
Even if this was possible, that's no way to live. Wasting the prime years of your life working sunup to sundown is not a ticket to happiness.
