The situation here is very simple. First you have to make savings then invest. If you limit yourself only to savings, then you can never count on significant success and income. Therefore, many people simply have no choice.
I think he means overall plan in goal. There are some people who thinks: Just give me million and I'll spend my life as I wish. But on the second hand there are some people who are billionaires and even more, what they do? As I see almost everyone invests, only silly ones save. You may ask, you have million and lets spend life, why are you looking for new challanges. I would say that it's not so easy to be millionaire and a lot of people don't want to take that work what being a millionaire requires. You have to keep your money which is as hard as becoming a millionare or if you aren't wise in your job, you'll get poor pretty soon.
So to make it clear, I vote for investments. It has it's fun too, whole captivation is that you never stop, do and do a lot of things, create something new with your money and watch how it grows or maybe falls but at least you learn from it.
