I can promise you I am not experience anything remotely close to wage suppression or competition for employment. Perhaps this could be true for junior positions, but at the other end there are lots of opportunities available.

That being said if you honestly believe there is wage suppression then I recommend programming outside of office hours and getting as much practice as possible so that you can rise to a senior position where such problems are absent.

Tech companies like Google, Apple, etc. have a well known history in working together to suppress wages. You might be making a lot, but that doesn't mean you couldn't be making more.

That was just in the valley. I work for a company that makes more money than Google (Alphabet) and fortunately don't live anywhere near the valley. That also has nothing to do with immigration.

It impacted salaries for everyone in the industry. I don't live in the valley, and it impacted me.

I didn't say it had anything to do with immigration. But it does have to do with suppressing wages, which is what they comment you were replying to was suggesting as a motive. My point being that tech companies have a history of this.

If the high payers collude it has a knock on effect on the entire industry - its basic stats.

When some companies offered reduced wages, Facebook sucked up all the price-sensitive top talent for a few years, until companies got wise.

But not as high if there was no collusion
