On the subject of humanitarian aid, if we drastically cut the amount that we donate to other countries be it in emergency goods or just financial aid, that could make the UK's image extremely poor, especially as how just a couple of centuries ago we were exploiting the world for money to line our own pockets. We should definitely give back to the world, partly because of this.
Some of these arguments against foreign aid (such as "why do we send our money to India when they have a space program" etc.) don't take into account how much it helps the needy people in other countries. Take India for example (I have family who've been and lived there so I have a fair amount of second hand experience) while there is a burgeoning middle class in India, there's still a massive gap between the poor and the rest- slums are an incredibly common occurrence there while the closest you get to them in the EU are shanty towns of immigrants in Normandy etc.
While there are still needy people in the UK, they have access to housing, benefits, free accessible schooling, the NHS (it may be going down the drain at the moment but it's still much better than healthcare in some countries) and much better pay as the minimum wage is very high compared with other countries. There are kids in Vietnam, Thailand, Cambodia, Pakistan, China and indeed in India who earn as little as 80p a day (and even less) working in sweatshops, making trainers for the West, while potentially suffering from illnesses.
As well as this, they don't even have the ability to pull themselves out of this situation as school is often inaccessible for them- and even then they would not be able to go as their meager income is all that supports them and any younger siblings.
Humanitarian aid cuts are possibly the worst thing to do at this moment in time, seeing as upwards of 2,500 people have been killed in the recent earthquakes in Nepal with potentially thousands more injured. Nearly all of these people have lost their homes, people in Nepal's capital are living in tents and probably will be for some months. £5m has been given by us so far and I believe more should be given.
I understand that a lot of the aid is given to corrupt governments and it is not distributed properly, however it's a case of controlling who gets the aid after a thorough assessment rather than cutting it completely.
