Very true. Hard to know what not to love in a 1500 page bill that is a bunch of densely written diffs to the current laws. I would much prefer to read the thousands of pages of what the law actually says with the diffs applied.
Now on to answer your questions:
What not to love, The requirement to give 1099 forms to any business a company does 600 dollars worth of business with in a year. Imagine you are an independent truck owner - you drive around the country delivering goods. You fill up on diesel at various stops along the way buying 2-300 dollars worth of diesel at a stop. You are responsible for figuring out which companies (realize the gas stations are usually private small companies owned by local franchises) you bought 600 dollars worth of gas from, what their business location is (No - it isn't cheveron, and probably isn't on the receipt) and delivering the documents to them annually. How much will this paperwork cost you, what happens when you make a mistake (really, did you know that some guy owns a gas station in florida and north dakota for some unknown reason?) - what does this have to do with the delivery of health care anyway?
What not to love, The requirement to pay for a product merely for being alive in the country. As an older American, insurance is a great deal - I will spend more than 10-15K in healthcare costs a year. As a young single male, well - lets just say if I see a doctor this year, it is unusual, I am wasting all of my premium. I am forced to pay for this just for being alive in the country now
What not to love, All of the mandates on what coverage has to include. Let me guess, you add required services to a bid, you expect the price to go up. Seems normal to me
What not to love, All of the wheeling and dealing that went into getting all 60 democrats in the senate to vote yes, if you want "good" insurance that covers a lot of things, so it costs 10K a year - you have to pay extra (unless you are in a union). If you happen to live in a few states with smart senators that hold out, your state gets a break by not having to implement things that are required of the rest of the country (so we are all paying for Nebraska now - wish I lived there, or better wish my senator wasn't such a tow the party line guy that they didn't have to pay him off to get a yes vote out of him)
I could go on for a while... next time someone wants to vote on a 1500 page bill, lets give people enough time to read 1500 pages (3-4 days? I mean it would be your full time job) so we can actually know what is in the bill before it is voted on.
