I would have invested capital in banks and insurance companies. actually i would have “purchased” some shares too. they are safe and if i had the legal age (i’m 14) i would have done so. at least in malta, banks and insurance companies seem very prosperous
You have to ask yourself, what exactly did European Union acheive? Free market trade, i.e. free access of all products & services produced in any country to all countries in the EU (to be sold in any country i.e.).
So post EU, common man prospered by investing in ownership of commercial businesses, as compared to defense & entreprenurial businesses earlier.
