Well you can start by not complaining the next time an unemployment report comes out that doesnt coincide with your preconceived notions of how the economy is doing. Its by conducting these surveys among thousands of individuals each month that the government gets the household survey that Bush was praising during the time Dems were pushing the employer based survey.
Yeah, the old "everything not specifically authorized by the Consitution is unconstitutional" thing gets trotted out but basically everyone advocating it is a hypocrite; they've either advocated. or had benefit from, from a wide variety of government activities just as absent from the Consitution as Census surveys other than every ten years....
NASA is a good example. Do they feel the Apollo Moon Landings were unconstitutional? Not a scrap in the Constitution authorizing that or even hinting at authorizing that.
If the sole means of data collection by the government was an every 10 year headcount, there'd basically would be no ability for government to make a decision about anything.
