Back in the days when immigrants weren't illegal, and Unions were.

ok,now i'm really curious, but why does it seem like so many of the new skyscrapers are concrete? Is steel not as good? or more expensive or what?

Residential structures are typically made of reinforced concrete because it flexes less, thus making the living environment more livable (don't want the building swaying while you're trying to sleep or watch TV). Offices are usually steel because people can deal with a little more sway when they're working and its cheaper and quicker to build. Look at the pictures for the Trump Tower, Waterview, and Burj Dubai (all residential), and then look at the NY times tower, B.O.A.T. which are both offices and are mostly steel.

id have to think steel would be much more expensive. MY guess is concrete has just become the preferred method for workers and engineers.

You're close
Concrete is mainly used in residentials for sound insulation between the apartments. When you have a wall of 250mm thick it will weight over 500 kg/m2, this will absorb most of the sounds from the neighbouring apartment. Concrete walls also functions as a part of the stability of the tower. This way the core can be smaller or isn't needed any more, a connection between a concrete floor and a concrete wall can handle a momentum. With steel you don't have those options or are way more expensive. Steel is better for office buildings, as you can build columnless floors. This is because steel is much stronger than concrete so that your floors can weight much less.
