Maybe Daddy's paying for it.
Debt, debt and more debt. The nations love it because it helps keep the banking industry going. Whilst, at the same time, a person can save and get a meager 2.5% Interest on their Investments; it's shameful.
I learned a long time ago that debt is not too unlike a lead ballon that drags everyone down in the end. If I can't afford it I don't have it; that's where I am. To spend such an amount and spend 'X' number of years paying back the cash will never warrant such a debt that you mention here.
(My personal opinion, of course)
In some cultures the parents pay for the wedding....other than that....different people have different priorities.
Somebody else must be paying for the wedding.
