Possible? yes. A good idea? No.
Sometimes people get this notion in there head that because something is a percentage that it suddenly is equal in all respects and all situations "because it's a percent". You see this in the gun threads a lot. People literally can't comprehend that yes, total population matters and DOES effect the per 100,000 numbers, even though the per 100,000 statistic appears to take total size out of the equation. Anyone that has ever taken an intro to stats class understands these things.
That said, 10% for the young woman fresh out of school, making 45k and living in Brooklyn is NOT the same "skin in the game" as 10% on the Partner at her firm with an AGI of 25m living in Manhattan. The percentage is the same, and it's flat so it's "fair", but the young woman who just left school is going to miss the $4500 more than the Partner will miss $250k.
A progressive tax, which we very much do have, even though lefties cry to the mountain tops we don't, they don't know wtf they are talking about, is a better way, if we're taxing incomes. Are there changes I would make? Yeah, absolutely. But I wouldn't change it to a flat tax, and I would avoid words such as "fair" and "patriotism" while doing it.
Loaded question lol.
Possible? Yeah, without question. Will we just end up right back where we are in a couple years? yeah, lol.
One of the pieces of advice i like to keep in mind is there is always going to be someone out there better than you at anything you do. (You know, stay humble, etc.) With this in mind, there are very, very smart business men and women out there that are also creative. Neither you, nor I nor anyone can write the perfect law that prevents creative people from innovation in the name of tax deferral. And that is a GOOD thing. I'm glad people want to keep their money, lol.
So end of the day, yes there is a ton of fat we could trim, but much like your typical american, we'll gain a lot of it back, if not more.
After I read Bush's I gave up. It's a lot of fluff that seems specific but has zero substance and just sets them up for lefty propaganda. Our current code makes anyone proposing lower taxes look like they are in the "bag for the rich". Because THE RICH PAY ALL THE FUCKING TAX lol. Even Bush43's cuts lowered taxes for every single fucking quintile, and total revenues increased. What do the lefty's cry? "Bush's tax cuts for the rich". Those ignorant cunts make me hate election season on social media. Everyone Tom Dick and Harry suddenly has an MST and 22 years of tax experience because they read some meme that is 100% bullshit.
