We are on the cusp of a financial crisis, so many are rightly reluctant to part with their money, however, as any economist will tell you the best thing to do when racing towards a recession is to spend spend spend, but the key is to buy things that have value and will hold that value.
Buy things that people will need. If we have a crash like the one in 1929, and all the signs are pointing towards something on that scale, then money in the bank will not be worth the paper it's written on, or rather it will be worth exactly all of the gold that it's not backed by.
Banks die and money has a habit of inflating itself away, that is how they will attempt to navigate out of the mess they created. The world is full of people up to their ears in debt, things like cars will become simply untenable for most normal people, either because the payments can't be met or the fuel they need becomes too expensive, and that includes electricity for e-cars, which is already on the way to being more expensive than petrol at cost price, never mind the batteries which are already on the way to costing more than the rest of the car.
Bikes, and specifically robust, reliable, easy to maintain bikes and parts will soon be worth their weight in gold.
And that's how I explain to my Mrs why the garage, shed and back room are filled to the ceilings with them.
