I understand. I assume you paid them well for fair work hours under good conditions, provided for all the safety precautions, worker’s compensation, proper healthcare and all the good things a decent employer would do? Paid taxes on your income to fund the infrastructure you’re using?
In that case, yes, you’re a good samaritan and got shafted by an unfair system.
Doesn’t change the fact that scientific data suggests all those Covid measures had some impact, but I’ll take back my cheap labor comment then.
