Most studies indeed show that the effects on the economy are more detrimental when income taxes are increased than with an equivalent increase in sales taxes. If you are looking for a strategy that will encourage investment, returning to work and savings, an increase in income taxes, either corporate or personal, individual tax will constitute an obstacle to investment and to a return to work. That is not the case with an increase in sales tax. That has more influence on the use consumers make of the goods.
So, yes, it is a strategy that we would like to advocate.
