There's also the simple fact that marriage usually improves upward economic mobility and even outright creates wealth in some cases:

* If you're both employed, the higher earner could potentially be pulled down into a lower tax bracket

* If at least one spouse is salaried, the employer's insurance can often be shared at a reduced cost

* If both are salaried, the market of insurance policies you have to choose from essentially doubles

* If you're renting, you can essentially halve the cost of living (assuming dual income of some kind)

* If you're looking for a car or home, you can usually qualify for better loans (assuming neither spouse is a credit disaster)
