The Constitution, unamended is a fairly simple document, giving the rules for creating and administering laws, and stating what things the Congress could and could not legislate, and how to amend (i.e., change) the Constitution itself. It was meant to be simple and straightforward. Then, folks noticed that maybe it would be a good idea if the Constitution clearly stated bad things the government should not do, like control speech or confiscate firearms.
After a while, slavery going out of fashion, it was decided to make that illegal, and to insure the rights of freedmen.
Then it just got silly, with the government bursting out of its seams and taking on more and more responsibility for things it cannot do, and should not try, and the Supreme Court rubberstamping every gimcrack hairbrained notion some Ivy League professor could dream up and get the New York Times to endorse.
Nearly 50 years ago we had the IADC standard land drilling contract. It was four legal pages with one page devoted entirely to columns of items and 'X' and 'O' for who provides what. It had worked well all through the 50s and 60s. So far as I know it still exists but the last contract I signed was more than 20 pages plus amendments and master service contract all totaling to nearly 100 pages. It still does the same thing it did 50 years ago and the X and O page is still the most frequently referenced aside from the weasel words in the repair hours clause.
Now the contract is even more complicated since we have to deal with responsibility for such things as who has caused the PTSD claimed by many who say it is caused by hurricane evacuations and such. Strange how the whole crew came down with the malady just after the rig was stacked. Go figure.
As for government expansion. Without boundaries, specific mission and limited people organizations will always morph to waste. It being too time consuming to sort out the necessary from the chaff the most expedient solution is to whack away with a mostly indiscreet machete and build back from there. There will be unintended victims but the greater good will be served. Give a person a job and without specifics he will justify it somehow to survive. Give them enough rope and money and they will build empires. This government has too many people on the payroll, has given them too much rope and FAR too much money. We have far far to many empires of waste, fraud and abuse. People who have serious jobs and plenty of necessary things to do usually don't get into mischief or minding someone else's business.
