I think it has more to do with developers building 1BR units than 2,3, or 4BR apartments. For example, there is no shortage of studio and 1BR flats in London or Paris. But if you have a small family and need 2BR, well, the market demands what it demands. Friends of ours even went so far as to buy 2 1BR that were above and below, knock a hole out and put in a staircase. We thought of doing the same, buy 2 adjoining studio flats. We lucked into an abandoned apartment (which presented some other problems).
