I think you answered your own question. You pay for quality.
That said, this is America and we have a competitive capitalist market. Consumers have legitimate choices in price and level of quality.
A solid hardwood cabinet with granite top is better than a laminated plywood with melamine doors and cultured marble top. Are there millions of the latter in service everyday, with adequate appearance and endurance??? YES. SO, you evaluate your preferences, what you want in terms of materials and workmanship, then factor in your budget and make a decision. What a country!
