I'll take a stab at it. H.R.25 (the Fair Tax Act) would be a good solution in my opinion, but Pres. Biden has threatened to veto it if it passes. If you aren't yet aware, the Fair Tax has been proposed in Congress regularly since around 2005 but has never seen a vote. The Democrats/mainstream media try to paint it as a 30% regressive tax that will increase the middle-class tax burden. But if you read the actual bill, you'll find out why it's never seen a vote and why politicians hate it so much: it takes lobbyist money out of their pockets and takes away the control they exert with the IRS. The bill completely does away with the incompetent IRS (which fails to collect a TRILLION dollars of owed taxes each year: https://www.reuters.com/article/us-usa-treasury-irs/irs-chief-says-1-trillion-in-taxes-goes-uncollected-every-year-idUSKBN2C0255) which costs over $12 billion to fund each year. This means there will be no federal income tax or payroll taxes withheld from your paycheck and you won't have to file federal taxes each year (it gets rid of capital gains taxes as well). The Fair Tax is also progressive in the sense that everyone (every registered household) will receive a monthly prebate (rebate) check to cover purchases of necessities up to the federal poverty level. This effectively makes the tax rate 0% up to the poverty level and then it staggers up to 23% based on what you buy. This is key because it encourages saving money and purchasing used goods since the tax will only be levied on new goods and services. You are now in control of your tax rate based on what you choose to buy or not buy.
The Fair Tax would get rid of tens of thousands of pages of IRS tax code and replace it with 100-200 pages of tax code. Politicians don't like it because it closes all the tax loopholes people like Warren Buffet and Donald Trump use to pay less taxes than middle-class Americans. It also get rid of corporate (and export) taxes (which only get passed through to the consumer anyway). This will bring businesses and jobs back to American soil because there will be no reason to move them offshore any longer (except maybe wages for labor). It is also fair because everyone (regardless of income) pays the same rate. This is important because we are recently seeing a huge jump in rich people moving overseas to avoid taxation (https://calbizjournal.com/why-wealthy-people-are-giving-up-their-american-citizenship/). Also, it will potentially bring in more money because all the people that don't pay taxes now (career criminals, undocumented immigrants, pimps, etc.) will then be paying sales tax at the register for new goods/services. Most states are already equipped to collect sales tax so it won't be a huge transition. I wish people would spin the monthly prebate checks as "reparations" because then lots more people might support it. 🙂 Wikipedia has a lot of the details regarding the amount of the prebate checks, etc.: https://en.wikipedia.org/wiki/FairTax.
