I realize now that most of the financial decisions I have to make now for the long term (for example, whether to buy an apartment on credit) depends on what the world economy is going to get in the next few years : inflation or deflation ? In case of inflation it will be better to de indebted at the current low rates. In case of deflation it will be better not to be indebted, especially since in this context, the value of the home will probably go down, or at least not rise further. Of course we can also imagine price stability. In that case the value of the investment alone will have to be considered. Which is an important factor in any case. Economics is a tricky science, and it is very difficult to predict anything in that area. But I feel it is necessary, and it is something that I like to do.
