Prices for most things in Romania are the same as in London but the income is a lot less that's what puts most Romanians in a nasty situation.
Imagine you living on (average us income)/6 while everything else around you has the same price it has now. That will give you a good idea.
Most people have a monthly income of about £250 if you were to convert it. Now that should cover all the bills and food, most Romanians own their houses so they don't have to pay rent which is good but that is still a bad situation regardless.
