'I have a detailed plan"

I have now seen ads for various candidates this year who have said 'i have a detailed plan for bringing back jobs." Why don't most of the politicians tell us at least a bit about their plans? Somehow, I do no think that the plans are the same for all candidates. It may be true that 30 seconds is not long enough for explaining a plan. But how about a series of commercials that identify 5 different actions that can be taken to "bring back jobs". Each one could get its own commercial. It would be so different to actually treat the voters with respect, that I think the ads would work.
