Workers are not greedy for simply needing enough money to rent or own a home! In the same time frame, average US-wide rent has gone up from ~200$ to 1100$ [1] - that's a 450% increase. In "hot" areas such as SF, the development has been even worse [2]. On top of that, other necessities of life such as groceries have also continuously gotten more and more expensive [3], not to mention more expensive to obtain as neighborhood grocery stores closed down in favor of large malls.
We're talking about bare survival here. The costs of living have exploded for decades, while wages have been stagnant. People couldn't set aside money as a result, and now we have over half the US population unable to cover a 1000$ emergency without going into (even more) debt [4]. Wanting more money is not greed in these conditions.

Additionally, the standing of unions went down over time, as a combination of legitimate unions-gone-rogue scandals, anti-union legislation being enacted and union-protection enforcement being reduced.
The result was that the capitalist owner and leadership class enjoyed absurd amounts of net worth gains, and the worker class was left unemployed or with stagnating wages at best. To prove that: CEO payments exploded 940% since 1978, S&P went up 707%, while average worker pay went up only 12% [1] in the same time frame.
