I don't think this is completely valid. I know a handful of people I graduated with both undergrad and grad, who went into industry for a year or two and then went back to study for a PhD. I wouldn't say it's a common path, but it happens..
In your case, you may benefit from a 2 year stint in the workforce IMHO
In practice, I expect most people will, if nothing else, find it hard to give up a likely fairly lucrative job in an on-demand profession to get a PhD. Golden handcuffs and all that.
