<human>: Can you provide a brief rundown of the text in within 3 sentences?

This is the situation I am in, however I'm going to write it in 2nd person to maybe paint a better picture.

Imagine you worked at a mid-sized company as a software developer for 10 years and made a good living, then were suddenly downsized due to a parent entity taking over operations and leaving you as a maintenance/legacy code monkey. You've accumulated a wealth of knowledge and developed a great rapport with most of your coworkers, however the writing is on the wall...it's only a matter of time before you are let go as well. Saddened and a bit disgruntled, you beat them to the punch and move on to a different company: a much larger, stable company that has room for advancement, decent (read: standard) benefits. You're making a good paycheck, work with happy, reliable people and for the most part enjoy your job - except it's a massive corporate entity (think Initech). You are looked up to in the company by your supervisors, managers and peers, though the truth of the matter is the sea of code monkeys that you work with have no idea what they are doing. You aren't expendable, but deep down you know you aren't doing anything a properly skilled software developer couldn't do.

Years later, you get a phone call from the previous company. Things have turned around, the company was overtaken by a larger entity and are looking for skilled people with some domain knowledge...specifically former employees. They've doubled their yearly revenue and are in a much more secure/stable position then ever. They offer you a project management position that pays 20% more than you are currently making per year and a signing bonus. 

What do you do? The end of your previous tenure leaves a bad taste in your mouth, but the skills you possess and desire to move up is strong. Is going back to the previous employer a bad idea?
<bot>: Employee was downsized at one company, moved on to a more stable company, but then asked to come back to a better position at a higher salary after the economy improved.
