You seem to be somewhat uninformed for a Jr. High student. At the conclusion of WWII it was determined by our civilian leaders that future wars would not allow the nation to call up, train, and equip the military for defense of our nation in the event of a general war. In fact with the advent of the long range bomber and intercontinental missiles we couldn't even be safe without outposts in other nations and our foreign territories. Prior to WWII this type of policy was limited to the US Navy, modern warfare made it an integral part of our philosophy. It involved no surrender of individual or states rights.
With regards to mergers, were they? Or were they shot down to prevent competition with various campaign donors and "favorable" corporations? AT&T and T-Mobile would not have decreased competition since they didn't compete - Obamas DOJ was "worried" about net neutrality - which had never been a problem over the 30 year history of the public Internet. Other questions were raised because AT&Ts CEO was a free-market Republican...… buying a Democrat-friendly corporation..... Then you've got the sweetheart GM/Chrysler bankruptcies, presidential interference with a bankruptcy and ignoring precedence of payment to reward the union and punish investors and non-union subsidiaries? Solyndra getting a half-billion to help donors to cash out before the bankruptcy? Crony capitalism is bad.
So no stories of mass poisonings and death by food. Didn't think so. As I said, the FDA has a job to do, it's just not as impactful as you claimed. Prior to 1902 the individual states had responsibility of determining the safety of various chemicals. Patent medicines were tested, and like most things in small doses were somewhat effective. I remember using Mercurochrome and Methiolate to treat cuts into the 1970s, the FDA effectively killed them in the 1990s. We don't treat cuts and open sores with mercury anymore..... So the FDA caught some and allowed some to go through, you've got a nice story but didn't really address your claims now did you?
The FDA approved the opiods, the FDA set the standards for prescribing them, the FDA oversees the effectiveness and the side effect analysis...…. now the government needs to get bigger to correct a problem that the FDA allowed to get bigger...… you see my point? Government can't lower the price of insulin, they aren't responsible for its R&D, its manufacture, the cost of certification, etc. There ARE cheaper insulins out there, we've used insulin to treat diabetes for nearly 100 years. The question is what's approved for use today and when they are superseded by newer medications and newer delivery methods. People want the pens and not the vials and the syringes and the refrigeration...…
With regards to child labor laws - you understand that children were working in the factories because their parents needed/wanted them to. Children made up almost 20% of the non-farm labor force. It wasn't evil corporations that forced them to, it was the poverty they were trying to escape from and prior to the industrial revolution child labor was on the farm or around the house. Most of the nation was in poverty and poverty is a motivator. But the states began enacting laws to limit child labor as early as 1848. Various states did ban child labor in the early 20th century, but others didn't. In the 1920s and 1930s child labor was on the decline because adults were looking for jobs and unions were pushing for adult laborers. The federal government attempted child labor laws in 1916 and it was struck down by SCOTUS. A Constitutional Amendment passed Congress but failed to be ratified by the states in 1924. It wasn't until 1938 that FDR got a law passed that was able to pass Constitutional muster (of course his SCOTUS was hand-picked) to take away what had been a state and local power.
