Yes do agree, integrate it into one tax based on what one earns .
Its all well in good , as people are more fit and bale now , but we need to do something about how folk can earn a state pension , works pension and a wage ??
The keeping folk in work to a very later age, is impacting on young peoples job opportunities , I am aware of a few folks with this triple whammy earning of state /works pension plus still in work wages ?
