&gt; Over 50% of government expenditure is on social security, medicare, medicaid, welfare, and other social services.<p>This is wrong (unless your definition of social services is  broad enough to include things like schools and I doubt you want to dismantle the public education system).<p>&gt;  A large percentage of that is inefficient and wasted.<p>This is also wrong. Social Security is a direct cash transfer and Medicare and Medicaid are among the most efficient insurance programs in the world.<p>&gt; I imagine state taxes would go down as a result of UBI too.<p>Sometimes I like to imagine a world of dragons and unicorns. But then I wake up and resume living in the real world.<p>Do the math.
