The difference is my desperation for the job. I had to pay for my studies back when 1$ an hour seemed like more than nothing.
Now working for less than 50$ feels like being exploited. This is the matter of perspective and situation in life, you can never fix it for everyone in the world. There will always will be people like me who will work for 1$ an hour because they have needs to meet and scholarships or handouts don't make up for it all.
