Is starting my own business venture or investing in someone else's business , the only way to get rich ? I am not looking to become rich quick. I am in no hurry. What are the other options available ?
Not at all. The Millionaire Next Door offers a book full of anecdotes on couples that earned money and saved their way to being millionaires. I believe about 1/3 or so had businesses, but the rest were employed and simply saved wisely. $3860/yr saved for 40 years at 8% will return $1M. Adjust the numbers to hit a million sooner or reach a higher goal.
The Author might be accused of survey bias. This is the phenomenon of studying the final results without looking at the pool of people years prior. Little Adv' is correct that while 1/3 of millionaires may have gotten that way by starting a business, that says nothing about how many businesses need to start to find the one millionaire that resulted. I view the book more as a lesson of "spend beneath your means" and focus on his anecdotes of the dual income couples who saved their way to this status. If you are in no rush, get this book from your library and spend the few hours to read it.
In response to my Friend Dilip's comment, MoneyChimp offers a good look at compound growth (for the S&P) over time. The 40 years ending 2012, which obviously include the 'lost decade,' returned a CAGR of 9.78%. Not to be confused with the average 11.43%. When I pull the numbers for each year's return and apply an annual $3860 deposit, the 40 years ends with $2.2M. A 1% fee, or 1% lower return resulted in $1.6M.
If 8% isn't conservative, of course you can run the numbers you wish. The 40 years contained both a lost decade and two great ones. Will the 3 decades post-lost average to get the Quad-Decade period to 8%+? I don't know.
That's actually a pretty good way to get bankrupt quick. You can get rich quick through lottery, gambling, mere saving or investing wisely, or marrying someone from the Kennedy or Bush clans. Starting a business is one of the ways to become a millionaire, but definitely not the only one.
