Are there any lazy occupations?

Today I listened to a radio programme discussing how the Spanish empire declined, the programme thinks that the Spanish empire decline is caused by its economic structure at the moment and the way it gained its wealth. The programme believes the Spanish empire's success of conquering America led to its dependence of gold mining and also led people to believing in the possibility of surprising wealth thus laziness in the country. This argument has its reasonable and does have some evidence to back it.

From this argument it is possible for us to conclude one argument which is an effective  way to earn wealth makes people lazy. Here effectiveness is defined as a ratio of inputs to outputs. Once people are possible to seek a way to use limited resources to generate enormous profits, people in the economy are likely to become lazier.

When people are considering one of such methods, I believe many people would have many ideas. However, i think there is almost no such lazy occupation. Firstly information is much open and easy to access. This prevents a particular group from hiding information about lazy jobs. Once more people go to the lazy industry, more requirements are made and this increases the potential costs of people. Secondly, when more and more people receive higher and higher incomes on average, the opportunity costs for any job increase. Therefore, the costs and inputs for these lazy jobs are increasing over time and the jobs become not lazy any more. 

However, there is one job that could be seen as lazy job. This is capitalist. Especially in the western world, there is a group of capitalists. Their wealth is put into wealth management firms and their incomes only comes from their capitals. However, they do not input any of their other resources. When they have large amounts of resources, the costs and risks of impacting their actual life standards almost does not exist. This is only one lazy job with a very high entry bar I think.
