Is it common that all ball joints need to be replaced after 50,000 miles?

What is your question?

I have just been advised that all the ball joints need to be replaced on my 2012 Chevy Silverado 2500 HD after only 50,000 miles. This truck has only been driven on highways and never used for rough work. Is it common that ball joints need to be replaced so soon? Apparently I need a wheel alignment, but the ball joints should be done first. What do you think??
