Progressive tax brackets. Basically, if you had an income of $80k&#x2F;yr before UBI, and UBI is $10k&#x2F;yr, you&#x27;d get taxed on $90k&#x2F;yr worth of income.<p>Current tax rates on UBI-only levels of income is basically zero.<p>It&#x27;s essentially a way to get higher income people to pay more for UBI without having what is easy to interpret as a tax increase.
