When minimum wage is increased (within sane limits) poor and middle class take home more pay while rich spend more.
If that were even remotely true, there wouldn't be a constant call to raise minimum wage. Think how many times it has been raised in your lifetime - over 8 to 12 times depending on your age.
This is just basic economics - not to mention common sense. When you raise minimum wage, business raises their prices to cover the new costs of labor. Those increased costs for products and services mean that the minimum wage worker is no further ahead (and will actually fall further behind at some point as they enter a higher tax bracket). All minimum wage increases do is cause artificial inflation and devalue the dollar for everyone.
