Changing of the Federal Sales Tax and removing Income Tax would benefit many people.
By removing the Income Tax would then raise the Federal Sales Tax to about 20% it would then allow people more freedom to save or spend money.
This would let people make the decision to purchase the items they truly need. By doing this people may stop and think if that item is a necessity. The only exception to this change would be food, food would still not be taxed.
Those who buy more items and those who buy more expensive items would be the ones paying more taxes.
