Sea2, chill, man. Let me guess, you're self employed?
Unions have definitively improved the working conditions (safety) and compensation for millions of workers over the last century. Is it really that complicated for you to understand that having a safer, healthier workplace and receiving better compensation would make you a more loyal and eager worker every day?
Of course some unions are just a total waste of space, doing nothing and taking dues. And even harming companies bottom lines. We all know this. But it's certainly not all, or even most unions. People like their unions and vote to stay in them, paying them part of their own paychecks. And seek out union jobs just to do this. Ask yourself, why? Just to bankrupt the very companies they work for?
I don't always have the data, or flexibility to make a direct choice, but as a consumer: I would rather buy products from companies where management has a healthy relationship with their union workforce. Where everyone can take pride in what they do, earn a decent living, and keep the middle class alive in this country.
