Suprise suprise. Lower taxes mean more money in the consumers pocket. More money in the pocket means they buy more. I always thought that was obvious. Maybe someone should tell congress.
But it is much more than just that.
Sure lower taxes are found money for the average tax payer.
But lowing taxes lowers prices making the money in the people's hand worth more in purchasing power.
Prices on the shelf reflect costs, profit, and taxes (all taxes including pay roll, income, property, fuel.....&)
if you lower taxes (payroll, income, property, inventory) you will lower the price and demand for those goods will go up.
Higher demand of people willing and able to pay for those goods increase production and that creates jobs and higher wages that makes more demands for goods, creating more jobs and on and on. Lowering taxes brings more $ in total to the government in taxes. 5% of 100 is more than 30% of 10.
