Headscratchers / The Wonder Years

• In "Our Miss White", Jack has to pick Kevin up from rehearsals because that's the time that Norma cooks dinner at. But Paul is also acting in the play. Since the two live on the same street, why didn't they think to just have Kevin ride home with Paul? Paul must have a ride, because he doesn't ride home with Kevin.
• Why were the Arnolds always so pressed for cash? Jack's position at NORCOM was as a manager which in a company as large as NORCOM is implied to be, should come with a quite decent salary. And the Arnolds had no extravagant expenses, so why did they always appeared to be living paycheck to paycheck?
