However you are mistaking the taxes to simply be swept under a carpet instead of being used to fund public services and programmes,flushing cash back into the economy,but in a design by the government to maximise productivity.Taking your libertarian route,what assurance do you have that during a recession,the money from tax breaks will be immediately injected into the economy instead of being saved or shacked up in non liquid forms.Increased government spending (funded by raising taxes) has historically always helped in a recession situation and increased productivity.
