Talk about missing the forest for the trees. The bottom 50% saw a 0.2% increase (to just 21%) over 5 years. OK, this is technically more, but it is a paltry increase of a tiny base spread out across so many people. It is reasonably seemingly imperceivable to any individual in the group. The top 10%'s increase, on the other hand, was greater than this. A greater percentage increase on a slice of pie that was almost twice as big. In the larger context, this just shows greater inequality.
If people are saying they feel the squeeze, even in social media comments, they are probably being honest.
