The Paradox of the 24% Tax Credit

The Biden administration has built certain carats into the provisions of the IRA in order to ensure a better labor rights or better pay. I would be really curious to know, but I haven't seen the data, to what extent are they announced IRA private investments? What percentage is really following or really using the 24% tax credit? Is it really possible that to bribe private capital into making working conditions better for labor?I have some doubts about that, but I also know being in Europe that our trade unions were looking with very envious, the Biden administration process of working with unions.
