You'll be hard-pressed to find a savings account paying 3% for a while. Hell, my mortgage is less than 3%. You're going to have to venture into riskier bonds (corporate, municipal, etc) or stocks to find a return greater than 3% right now.
Besides, if you put your money into any investment vehicle earning 3%, you're doing no better than keeping up with inflation anyway, and that doesn't even factor in the taxes you'll pay on your meager returns.
I've got a savings account with 3% interest... So either I got lucky, or you're just wrong.
I also love how 270k a year is "meager returns"
I've already stated that 3% is simply a base bark, I know i can get 3% yearly, and as others have said, 10% is possible if you know what you're doing.
Point is, it's possible to win 10mil, and simply live off the interest generated from such an amount.
I don't know where you found a savings account that returns 3%, so count yourself lucky in that regard.
The fact still remains that 3% annual return is only keeping up with inflation, so your purchasing power is going to erode over time.
