Tax does help people. I was able to not die from hunger while I was unemployed
Realistically only small fractions of our taxes go to things like unemployment.
Additionally, higher taxes means paycheck-to-paycheck lifestyles become more
common, which in turn means people have less to donate to charity or give to the
poor. It also means they have less money to spend on 'extra' things that could
get the unemployed employed.
Besides, inefficiency, corruption, over-bureaucratic perspectives, and a general
unwillingness to change with the times are rampant in our government. I would
rather take my chance on people than give in to government control which I know
will fail.
