If you see Basic Income as a negative tax, it turns a flat tax rate into a smooth progressive curve.<p>Let&#x27;s suppose a BI of $1000&#x2F;month and a 50% flat tax.<p>Someone without a job gets $1000&#x2F;month.<p>Someone with a $1000&#x2F;month job pays $500, gets $1000, ends up with $1500&#x2F;month.<p>Someone with a $2000&#x2F;month job pays $1000, gets $1000, ends up with $2000&#x2F;month, paying effectively no taxes.<p>Someone with a $4000&#x2F;month job pays $2000, gets $1000, ends up with $3000&#x2F;month, paying effectively 25% taxes.<p>Someone with a $10000&#x2F;month job pays $5000, gets $1000, ends up with $6000&#x2F;month, paying effectively 40% taxes.<p>Note that I&#x27;m not opposed to keeping progressive taxation on top of the BI. I just think it&#x27;s not really necessary anymore, and it could be used to convince conservatives to give this a try.
