Anyone else get irrationally angry at Lego prices?

Why does a single set cost $80?? My 7yo wants the new Star Wars thing and I'm looking at the price tag like it's a personal attack. I get it—they're building blocks, blah blah quality—but COME ON. There's gotta be a better alternative that doesn't make me feel like I'm funding some evil empire. Currently considering just buying him socks instead
