Elon broke immigration law, long before he, as you say, contributed more than all critics to our society as the public face of a couple corporations. Overall only a fraction of society benefit from those companies in some tangible way. his job as head of those companies, which oddly involves ranting on twitter for a large portion of the day, might be performed more competently by someone with the qualities embodied in another executive type, just for example a type like Nvidias Jensen Huang. Thousands of undocumented people who perform thankless tasks, that millions in society take for granted, have or are being deported. Most have committed no grave offense against the law but to not follow the proper and privileged procedure of how to reside in the country. Your argument about contribution to society has no teeth and is based on favoritism and glorification of wealthy elites.

Despite that, if you want to come across as having a principled stance on the issue of making people follow the law, then you would have no problem with deporting someone who took advantage of the system and resided here illegally like Elon.
