I'm not a VC or founder. I'm a developer just like you, trying to deliver cool products—but doing so requires more developers.
If my company was trying to suppress wages, or refused to pay above market, then I'd agree with you that we have no right to ask for more talent. But we're perfectly willing to pay for talent—we just can't find any.
I wouldn't be surprised if the number of senior developers on the market was less than 10% of the number of open positions.
