I’m not just talking about the $600 billion or so already committed under the TARP. There are also the huge credit lines extended by the Federal Reserve; large-scale lending by Federal Home Loan Banks; the taxpayer-financed payoffs of A.I.G. contracts; the vast expansion of F.D.I.C. guarantees; and, more broadly, the implicit backing provided to every financial firm considered too big, or too strategic, to fail.

One can argue that it’s necessary to rescue Wall Street to protect the economy as a whole  and in fact I agree. But given all that taxpayer money on the line, financial firms should be acting like public utilities, not returning to the practices and paychecks of 2007.

Furthermore, paying vast sums to wheeler-dealers isn’t just outrageous; it’s dangerous. Why, after all, did bankers take such huge risks? Because success  or even the temporary appearance of success  offered such gigantic rewards: even executives who blew up their companies could and did walk away with hundreds of millions. Now we’re seeing similar rewards offered to people who can play their risky games with federal backing.

So what’s going on here? Why are paychecks heading for the stratosphere again? Claims that firms have to pay these salaries to retain their best people aren’t plausible: with employment in the financial sector plunging, where are those people going to go?

No, the real reason financial firms are paying big again is simply because they can. They’re making money again (although not as much as they claim), and why not? After all, they can borrow cheaply, thanks to all those federal guarantees, and lend at much higher rates. So it’s eat, drink and be merry, for tomorrow you may be regulated.

Or maybe not. There’s a palpable sense in the financial press that the storm has passed: stocks are up, the economy’s nose-dive may be leveling off, and the Obama administration will probably let the bankers off with nothing more than a few stern speeches. Rightly or wrongly, the bankers seem to believe that a return to business as usual is just around the corner.

We can only hope that our leaders prove them wrong, and carry through with real reform. In 2008, overpaid bankers taking big risks with other people’s money brought the world economy to its knees. The last thing we need is to give them a chance to do it all over again.
