Nowadays, it seems, you have to have bachelors and/or masters degree-level employment to own such stuff. America was a great nation with a heavy manufacturing and traditional industrial/building trades base. The Democrats largely let everybody in and his dog from abroad.
Can't blame just the Democrats. Plenty of Republicans created the laws that allowed us to get where we are. Why do you think illegals came here in the 1980s? Ronnie Reagan implemented the first amnesty that brought the flood. Companies that hired illegals for cheap bought politicians on both sides to keep the wheels turning.
