In the end, the problems I see are these:
Democrats and Republicans pull between 40 and 55% of the vote every Congressional election. That means any tax or spending plan is going to be a compromise to some degree, although the Democrats vote in unison far more often than the GOP. That alone makes it hard to create a budget that means any kind of fiscal discipline, and the tax code just gets more and more obscure.
Also, don't forget we are living in the says when our own tax money is used to pay lobbyists, who in turn pressure Congress critters to keep the budget porky. Given how those lobbyists promise cushy jobs as lobbyists to the CC's when they leave office, and it's a fool's dream to imagine even half the politicians will put duty to the nation ahead of their bank accounts.
And then there is the media, which hasn't been an honest reporter of news since my father was reading the papers and complaining about the crap that passes for 'journalism'. The one thing you can count on from mass media is that they will shill for more government and more spending.
So to actually address the problem, it's going to take four stages, all of which depend on a leadership making the case to the American people to enough support to keep the corrective going:
Stage One: Flamethrower
I like the DOGE concept, especially the idea of making clear to the bureaucrats that there will be sharp deep cuts to the budget. Put everything on the table, and force everyone to defend their budget. Then you gain support by letting departments keep what they need most, while making clear that if you cannot explain how you will be lean and effective, you will at least cost less to be useless idiots.
Stage Two: No Non-Essential Functions
Companies are backing off DEI because they are learning it does not make a company more diverse or inclusive, but the opposite, and it does nothing at all to help a business succeed. A smart company stays on mission and never forgets its core function. Government needs to do the same, stick to the primary job and stop trying to do more than it's core.
Stage Three: Redesign
Through more than four decades of work, I have often taken assumptions and forced groups to learn new, better ways to do the job, including finding ways to be more effective rather than just throw money at a problem. In three places I was able to significantly improve financial results and in one I had an important role in keeping the company from having to file for bankruptcy. Far too many people in government have no interest in innovation, efficiency, or changing anything from the way they did things forty years ago. Change may need to be forced, but once the team understands how the corrections will help, you can build a nucleus for success, even in government offices.
Stage Four: Commit to Duty
Some people think government employees only care about money and finding ways to spend as much time avoiding work as possible, but there are examples of excellence in various places. Despite the current crap for leadership now, the FBI had a strong and well-deserved reputation for Integrity and commitment to Duty for many years. Law Enforcement and First Responders are well known for their devotion to duty, and we haven't even touched the military. With proper leaders, almost any government office can be reformed to dedicate itself to core principles and serving the public. Make the government actually helpful and everyone wins. What we have now is more than a million Bidens soiling what good might otherwise come from government.
