My opinions: Abolish social security, abolish medicare, keep the FDA but allow unapproved treatments clearly marked as such(possibly require signing a document confirming they know it's unapproved, or require them to file some paperwork with the local government in order to allow unapproved treatments). Of course, you'll never actually get elected advocating the first two, since the elderly have a stranglehold on politicians.
A more electable opinion: Allow people to invest their government-mandated retirement accounts however they want: SS is required to be invested in treasury bonds, which are not what I would invest in.
We don't need the government propping up the news companies, either. Professionals can stay informed to issues relevant to their work by subscribing to a trade magazine. Local communities often congregate at a church or similar(abolish tax exemption for churches, while we're at it), and that's as good a place as any to talk politics or gossip about celebrities.
For purely factual local community items requiring action(new sidewalk repair ordinance requires 30% of houses to replace their sidewalk trees, there's an upcoming mayoral election, a real estate investor just bought the last empty lot in the city and is building a huge apartment complex, etc.) can be reported by the government through the city or county websites, or by mailing notices to everyone.
I also wouldn't mind a government-operated television channel, intended for government matters(the president making his state-of-the-union speech, results of elections, warnings about emergencies, a brief summary of recent Supreme Court rulings as they happen, etc.).
