The Tax cut... why should it work now

[Vick]

ok now that Wig and Colin (as well as many other fine minds) are here please give me a little help (maybe you can figure out the formula if there is one)

Is the current tax cut (actually a rebate as checks are going to be sent out) going to stimulate the economy enough to offset the reduction in the actual tax base ($ the gov have to spend) ?
Will the tax cut add more revenues to the tax base due to growth the rebate will provide?

I'm under stand supply side and trickle down (and am a fan of both)

But I'm also a firm believer in tax cuts/rebates should be equal to reductions in spending - then we don't have the situation we had in the late 70's- early 80's where the USA ran at a huge deficit (which caused the USA to use up available funds which gave us some inflation and higher interest rates - to some degree)
