This amount of money is certainly not much for Carlo, but for the nobility, it's still a lot. The new nobility, owing to their lack of substantial landholdings, depend entirely on industry and finance for their income.
This also makes Carlo place great importance on this initial public offering (IPO). If the stock of this railway company rises significantly, it means these new nobles can also profit, enriching their family wealth.
Both the new and old nobility are Spanish nobles, but because the new nobility was personally appointed by Carlo, he clearly has a closer relationship with them.
Of course, this might also be because the new nobility poses no threat to Carlo and instead serves as significant support.
The old nobility's foundational strength in Spain is too powerful, and sometimes they don't necessarily follow Carlo's commands. Compared to the less obedient old nobility, Carlo trusts the obedient new nobles more, even if they don't hold much power.
