I think everyone needs to chill out a bit about Leverage levels. First of all, some people like to gamble and throwing 3 or 4 grand in an account and taking a shot at a score is the whole point of these Forex shops. One could even make the arguement that a new trader who has a negative expectation profile, would be better served by trying to make a big score off of a few overly leveraged trades than grinding out 100's of small trades. Kind of like if you want to win 10,000 dollars at roulette you have a much better chance of doing it by betting 10K once than 50$ 200 times.
Not everyone is trying to be a career trader, control volatility, and achieve an impressive Sharpe Ratio. Is this wise? Probably not, but this is America, for the time being irresponsibility with one's own money is still legal.
And of course, if one were truly responsible and very risk adverse, the higher the leverage offered, the safer your money can be actually. Let's say you were a client of Refco, you could have kept a token amount of margin in your Forex account, Purchased T-bills with your total risk capital, parked the Bills in a segregated and legally gauranteed Futures account, and made transfers back and forth to fund your day to day trading. I would wager there are more than a few Refco customers who wish they had done just that.
I guess it's easier to just decry low margin requirements, sound like a disciplined trader, and not think things through. All I can say is that I wish IB offered 1000 to one. I could trade real prices, with a true ECN, and by storing my base capital in a regulated futures account eliminate 99.99999999% of my counterparty risk!!!
Just my two cents.
