Money from tax should be used where it is needed most. To spend it on broadband for the poor and rural areas is necessary to improve the condition of the folks here. If the poor and rural areas have no reach to obtain knowledge, than knowledge must reach out to them hence the broadband. With due knowledge, these folks will have the power to redefine their lives and improve their situation.
The internet opens doors, provide income opportunities and information on how to live our lives better. This is taxpayers money well spent.
