Trump wanted to cut income taxes for the poor down to 5% to 10%. That would have represented a real tax cut and policy far more effective and beneficial than UBI. Even without exploiting tax loopholes Warren Buffett went on record as paying 17% income taxes, which is far lower than what the poor pay. Based on the above: no the poor definitely do not have tax cuts and many taxes target them indirectly in ways that are not clearly visible / often ignored.
