There it is again: the same old tired bullshit which only shows your COMPLETE lack of understanding of the Constitution.
The preamble states the purpose for the Constitution. Articles I-VII, plus the B.O.R and following amendments state HOW we attain that purpose set out in the preamble. And, in the end, as is supported by the ENTIRETY of the Constitution, the baseline method to achieve the goals of forming a more perfect union, establishing justice, ensuring domestic tranquility, providing for the common defense, promoting the general welfare, (note the word PROMOTING, as opposed to the word PROVIDING which is used in the preceding phrase) and securing the blessings of liberty, are BEST met by designing a LIMITED central government with specified, enumerated powers, and with MOST governmental power (supposed to be) remaining with the states, with the people in charge of it all.
Note how the preamble is worded. ... IN ORDER TO (accomplish this set of goals, we) do ordain and establish this Constitution...
But you STILL won't (not don't, but WON'T) get it, will you? The Constitution itself, and the DESIGN of the government outlined in the Constitution, is HOW we are supposed to accomplish the goals set forth. It was NOT written so some lame brained big mommy government twit can come along and say "we're supposed to be promoting (read providing) for the general welfare, and that justifies these actions. Sorry, that simply does not wash. LIMITED central government, and guaranteed individual liberties are how we promote the general welfare, along with all the other goals.
