The sentiment you're expressing is quite common, especially among freelancers and independent workers. There's been a growing sense of dissatisfaction with the perceived lack of financial rewards in online work, particularly on platforms like YouTube, Twitch, TikTok, and other social media sites.

Several factors might be contributing to this negative sentiment:

1. **Changing expectations**: The rise of influencer marketing and online celebrity culture has created unrealistic expectations about how much money one can make online. This has led to disappointment when earnings don't meet these inflated expectations.

2. **Platform fees and commissions**: Many online platforms take a significant cut of the revenue generated by creators, leaving them with a smaller share than they might have expected.

3. **Competition and oversaturation**: The proliferation of online content has led to increased competition for viewers' attention. This can make it challenging for creators to stand out and earn a decent income.

4. **The "grind" mentality**: As you mentioned, some people feel they're working hard but not being adequately compensated for their efforts. This can lead to frustration and dissatisfaction.

Your suggestion that creators be more grateful is understandable, but it's also essential to acknowledge the challenges and difficulties many of them face. Perhaps a more constructive approach would be to encourage platforms to be more transparent about their revenue sharing models and to provide better support and resources for creators.
