Simply because people like you want the government to do it, and then others who do not want to work, or try to get an education, will live off the endeavours of others. Even Christ said that we would have the poor with us always.
Notice that the farmers, back then anyway, did not want money, food stamps, etc. All they wanted was seed so they could go back to doing what they did best, labor for a living. Notice that the people responded 10 fold, and did not demand that the government supply the welfare.
Now, in this day and age, we have a society where a large number feel that they have a "right" to results of anothers labor, and people like you promote that belief.
When I was driving truck I was talking to a security guard at the 76 truck stop in Ontario, Cal. We got to talking about this topic, and he told me of his daughter. She had 5 kids by 5 different guys, and was on welfare. She was getting 1800 a month, food stamps, rental assistance, and free medical. As he said, she was living better then he, a working man, and had never worked a day in her life. He was pissed.
So, why should anyone work, or try to improve themselves, as long as people like you are promoting the very opposite?
