I am by no means a reference for financial matters, so I tend to think about big-picture macro-optimisations. In other words: what is fundamentally true, and must therefore always remain true?
One fundamental truth is that tangible, material assets will always outlast virtual assets. In an extreme financial crisis, owning a house is better than owning cash, for example. If you follow this reasoning to its logical conclusion, buying is better than investing (in the financial sense of the word). Or, if you prefer: invest in material assets that are of real use. Optimize these purchases to reduce your tax burden. Put yourself in a position to "hold out".
How far along this reasoning you go depends on your threat model.
