If only people would realise that, if they planned their income:expenditure ratios more carefully, most insurance would be entirely unnecessary.
Major investments and some vulnerable items do benefit, but generally only purchasing that which you can afford to replace or/and repair from saved reserves of cash can save a small fortune in unpaid insurance premiums.
Also, only items which are absolutely necessary or are income producing should ever be bought on credit or by loans; utilising easy access to borrowed money for discretionary spending is like adding another millstone to the restraints which dog those who lack self control and self organisation.
But it does make those people with spare money to invest increasingly wealthy, so it must be good for the "Economy".
