Exactly. Most employers are greedy (and cheap), so they will exploit employees to make them work harder without any substantial increase in the wage/salary. That's what we call a "burnout". And the situation is even worse in a physical setting. Telework (aka remote work) is more flexible. It's why many consider it to be the future of labor.
This is happened in everywhere, hence people who live in third world countries prefer to work abroad, at least even they're getting exploited in first world countries, they can still able to save a good amount when they back to their hometown.
This situation isn't getting better, poor people have no choice, they can only pray if their boss are humane and want to make their employees life better.
