They don't hate you, but you're probably not their favourite customer. The most profitable people are the ones that have high income and poor impulse control, who will buy an expensive thing periodically and then take a few months (at 10+% interest) to pay it off.
The people who put through a lot of purchases and pay promptly are the next best - they're charging the merchant 1-3% of the total purchase price to lend you the money for a month, which is a pretty good interest rate for the lender. I put a load of work expenses on my card and so last time I had an issue with a fee that I disputed, my card company immediately and without quibble cancelled the fee and added a good-will payment to my card, because the fee was about 5% of the profit that they make on me in a year.
For some card companies, the people who massively overspend are a good long-term investment. They get a (relatively cheap) court judgement against these people, which requires them to pay back a small amount each month for a very long term. It generally works out to 5-10% annual interest, but pretty much guaranteed over a 10-25 year period. The risk is very low and they're a steady stream of income for an up-front capital investment. This is why you get a lot of card companies advertising to students and other low-income groups.
