Most corporate gigs (if not all) will give you a better paycheck and cushy perks, unlike startups. They often come with extended hours and a hectic workload, which means that it may not be as glamorous as what you see in the movies. To many, staying in a harsh corporate environment may be mainly driven by the salary. More often than not, they would prefer to stick with what they know to be more stable. If that resonates with you, then a startup environment may not be the right fit for you.
