Should have vetted the numbers a bit better. In the 60's Nicklaus averaged over 20 tournaments a year, in the 70's he played 20 only once and in the 80's averaged only about 15 per year. Think Tiger only plays about 15-18 per year, which I think (?) is probably par for top players. Not sure about players a rung below, but even if they play 20-25, there should be ample time for family obligations if they schedule it right. I know myself , in season, I work 6 sometimes 7 days a week averaging 10 hours a day. In a seasonal business its the only way, bills and all that other stuff.
