Just look at the size of the UK credit card debt.
That went out the window ages ago which is getting more worrying as you get to the younger end of the working population.
There is nothing fundamentally wrong with a high amount of debt - assuming that debt is used to finance appreciating assets or is cheaper than outright purchase.
Where there is a problem is when you have "millenials" (or Corbyn voters as they could also be called) who have 10s thousands of educational debt and then 10k or more on credit cards accumulated with TopShop, TK Maxx purchases and rounds of cocktails in AllBarOne.
