WASHINGTON — Restaurants say they need $325 billion in federal assistance. Boeing wants $60 billion. The travel industry has requested $250 billion and manufacturers are seeking $1.4 trillion in loans to deal with the economic devastation being wrought by the coronavirus.

And that’s to say nothing of the casinos, airlines and franchise owners, all of whom have signaled that they, too, will need relief from the federal government to survive.

Then there are the industries and companies that do not immediately come to mind as front-line casualties but are nonetheless lobbying for their causes to be addressed as Congress prepares to allocate $1 trillion or more in response to the crisis.

The prospect of a bailout of a scale without precedent has set off a rush to the fiscal trough, with businesses enduring undeniable dislocation jostling with more opportunistic interests to ensure they get a share.
