should we give money to the beggars?

Today we debated on the pros and cons about the topic: should we give money to the beggars?

Pros:
-those people who is homeless, having no friends or family, destitute, disabled or jobless can support their life by using even a little money;
-reduce the criminal rate and keep the society stable;
-the existing welfare of our government is not completed enough to cover all of the people;
-providing you were the beggar, wouldn't you like others to give you money, even a piece of bread after a hunger having lasted for two days?
-to say the least, you will not be affected any way by losing such little money. But there existing the probability that such little money can change the beggar's life. If some of them can contribute to our country in the future, your money is much value added.

Cons:
-give such beggars the illusion that "No pain, still gain.", if such kind of behaviour were supported by us, there will be more and more people to quit job to beg. Perhaps they think they will earn more money like this；
-we can't tell who is the cheating and who is the real beggars;
-there is story about "fish and fishing" we can use to support this point. That is to say we should teach them to earn by working rather than give them money directly.

In my real life, I rarely give money to them. Definitely, they need help and we have the responsibility to help them. But I will help them in another way. Because I think it is not very easy to earn money, especially in such a tough time, the right money should be devoted on the right place. Perhaps I will subsidize one or two non-school children just because of lack of money.
