Should US companies be able to fire/layoff US citizens to hire a cheaper employee through H-1B visa ?

Yes. Companies should be able to layoff employees and hire cheaper ones, they need to keep costs low for shareholders.

You need to be indispensable to the company you work for, that comes with hard work... If you can be replaced by a cheaper worker who is just as good, then you probably aren't really entitled to your position in my eyes.
