She was willing to pay his mortgage, insurance and even his cable-TV bill, but JOAN LUNDEN was livid when a New York judge ordered her to pay $18,000 a month temporary alimony to her estranged husband Michael Krauss, an ex-ABC-TV producer who championed his wife's ascent to co-host of Good Morning America in 1980. "Why the courts don't tell a husband who has been living off his wife to go out and get a job is beyond my comprehension," said Lunden, who reportedly makes $2 million a year. Defending the lavish subsidy, Krauss's attorney said, "He's used to spending more than that. He deserves his share until he gets on his feet." With that kind of allowance, why would anyone bother sending out resumes?
