when has the government ever raised taxes on IRAs or 401ks? only in your imagination. it has raised taxes on social security benefits, but it hasn't (directly) reduced them. comparing the two is apples and oranges at best.
no. absolutely not. the potential benefit is a lowered tax burden NOW. and greater principal to invest. and a lowered tax burden during the investment period in the form of a tax exemption for gains and dividends. if you don't understand this basic point about retirement accounts, then you don't know what you're giving up in exchange for your paranoid feelings about future confiscation.
and the very rich don't have IRAs??? come on. check out mitt romney's financial disclosures. Roth IRAs are extremely popular among the very wealthy.
which of these has gone up - and only up - over the last 20 or so years? without knowing your state i can only comment on federal, and i have already many times. federal income tax rates have not gone up during the period since 1993. capital gains tax rates have not gone up in the period since 1986. if you make as much money as you claim to, these are by far the most important taxes.
other than that, provide some evidence for once. you are making naked claims. to the extent i can respond, i know your claims are false (i.e., with respect to federal taxes). so help us out, where is the proof for what you are claiming? you just have this gut feeling that you are being screwed, and that you will be screwed. my position is that your gut is wrong - just as it is about crime rates. can you prove me wrong?
you could pay the penalty and keep whatever insurance or lack thereof that you want. yes, that would be a tax increase, but you claim in another post that the risk of losing wealth due to a health problem is an issue. no, it's no longer an issue because of obamacare. be consistent.
