Why Doesn't Everyone Invest In Real Estate?

[Ryan Dao]

This might warrant some raised eyebrows but I always asked myself the same question: 

If real estate is a great way to become wealthy, why isn't everyone doing it?

Now I'm not saying investing in real estate is easy, because I know that it's not easy. I know that it requires a lot of hustle and grinding. However, I know a lot of people who work 3-4 jobs and easily work 60 hours a week. They obviously are determined to make money, and whether they are living paycheck to paycheck or not, why don't these people working so many shifts save up money to buy a house and slowly progress their way towards passive income? 

Is it because of fear of going further in debt? Is it because they don't know real estate investing exist? 

I always ask this question on Google but there's not an answer that answers it.
