The chancellor, Philip Hammond has reversed one of his key budget policies, but he needs to go further.

Mr Hammonds critics are wrong on this occasion. He fluffed up, he increased national insurance on the self-employed and the hornet's nest that was set loose led to an awful lot of stinging.

But Mr Hammond relented. That's okay, politicians have been getting it wrong, but refused to admit it, since the days we first had politicians. If more politicians owned up to their mistakes the world would be a better place.

Mr Hammond's U turn is refreshing, and don't criticise him too much, or politicians will be less open to a reversal of policy in the future.

But there is a wider point, and in this respect the penny has not yet dropped.

Not that Mr Hammond is alone in not experiencing this dropping penny.

Take for example, the words of Laura Gardner, an Economist at the Resolution Foundation. She said: that it was "disappointing . . . that the increase in class four national insurance won't be going ahead because that increase closes some of the discrepancies between employees and the self-employed in our tax system and it largely hit the better off self-employed with the lowest earning self-employed not being affected at all."

Now the Resolution Foundation publishes a lot of good work, but on this occasion, it got it wrong.

Let's look at the issues associated with being self-employed. No holiday pay, no sick pay, no employer pension contributions, no redundancy pay if you get laid off, minimal job security - if a company makes redundancies, getting rid of self-employed workers is much easier. And oh yes, problems getting paid. For many it is also the first rung on entrepreneur ladder.

Making it harder for the self-employed was absurd, but the government now needs to make it easier.
