When we are ready to accept free things on purchase why not free government education ? ?

Every year the central and state governments are earmarking lots of funds for the Sarv Shiksha Abhiyan which entitles free education for the poor and with free books and uniforms too. Generally we feel elated and happy to get some thing free on purchase of a product or service. So when the government is providing free education then why the people are not coming forward to avail the facility. The government has considerably increased standards in primary and high school sections and it is you and me should motivate the poor to avail the free education.
