It's not just that they're afraid of work. They're trying to take advantage of this crisis for at least two key political reasons. First, they want to jam through as many of their pet projects in these relief bills as they can squeeze in. But as we all know, you can't shove ten pounds of crap in a two pound bag. And possibly even more important to them, is dragging it out as long as possible, all the while making it as difficult as possible for Trump to deal with. If anyone thinks they don't want to use this against Trump in the upcoming election, then naive does not begin to describe your character.
A tertiary motivation is a fundamental change in how our society is structured, but I don't believe that will come in the way they'd like to see it. The economic bailout packages are essentially socialist. And people can see what the stores are like under this self imposed shut down. Only a blind fool would look at all this spending and believe that absent a crisis, it would have any positive impact on the country as a whole, and the economy specifically.
