In terms of war, well you’re right about that, but when it is about economy and investment, that’s just how it is; high risk means there is likely to be high profit. It is not everyone that invests in a high risk investment that is going to make profit, some people will face the high risk and some will profit, everybody is not going to win, except those that knows what they are doing. Even at that, no matter how good you are, there are still going to be times that you’re going to face the risk and lose.
So, you misinterpreted it, because in terms of economy and investment, it is high risk and high reward. But it is not the same for war, and war is totally different from investments, it is a thing of death and is a very bad thing. Only stupid people pray for war.
I agree, sure there are high risk and low reward stuff in the world as well which do not make sense and not many people do that but high risk/high reward things are abundant in the world and people take that risk all the time. Even quitting your job to start your own business is not a way to make a profit that easily, it is just very hard and very high risk so you are going to end up with a very big profit if you end up with the right business.
So long story short there are many things in life that causes you to take a risk and the reward is high, it is not even just business or money, even while buying a pillow you may pay a ton of money and take a risk and if you enjoy it a lot then you are doing great but if you end up with a bad pillow you don't enjoy then you paid for nothing. So, it basically means everything in life could include high risk and high reward.
